Never felt like this before

I've been seeing this guy for a few months now and i dunno what it is about him, he has this hold over me, or spell haha, who knows.
I've never felt this way before over a guy at least I dont think I have, I get butterflies  whenever I go to see him, I think that's kinda nice, to me he's practically perfect.
The list is endless  of what I love about him, and i dont just mean looks, I forgot how much I love a tall guy, he has amazing eyes and a great smile, his laugh is lovely,  I love his arms and im sure he also knows that,  his voice is just to die for.
He has an amazing personality ,he loves animals and has  such a kind heart i mean he gave me flowers ..on his birthday I just want to know more about him all the time, I'm very infatuated by him  but I'm at a point of insecurity, and I think If I don't get a hold of myself. I'm gonna lose him.. maybe it's guilt of the fact that I ended the last two relationships I'm now scared it's going to happen to me, I don't want to get hurt, I've not let down my wall completely yet..It may take a bit of time but  I'll get there.

Am I too picky?

I've done alot of thinking over the past few weeks, I mean I'm not sure if it's the logical part of my brain thinking or the little bit of insanity that goes on in there, but I keep thinking that I am but too picky when it comes to men.
I almost feel jealous for the people out there that has been seeing the same person for a good few years that look as though they got it good and perfect, but I also did say on my last post that you don't know what goes on in people's life's.. I'm sure they work at their relationships , however these people that from a far you look at and they look happy and in love , just moved in together,  can't keep their hands off each other , and engaged, pregnant yada yada yada!.
I envy them that's all I ever wanted I've never had all that  in one relationship ..in all 2 relationships I've been in, with John I got the physical contact and love but he just never seen me, once a week or even fortnight was not enough and the we seen each other less and less and i got use to being alone and it got to a point that dispite I had the title of being In a relationship.. I wasn't. With Chris I seen him all the time and had got the effection but just not much physical contact.. why cant i have both? One thing they were both the same with, is that it didnt matter if i voiced my concerns over matters ..they both were the same for communication, terrible.
I want it all ,not parts of a relationship ,im aware that noone is perfect but i think you got to have at least all that but like i said.. i feel as though i might be too picky  or maybe im just looking too much into things i don't think it's a bad thing that people have some specifics  in a guy .
I just want a guy that's head over heels in love with me as much as i am for him and that wants to spend time with me , can be, confident and romantic and sweet but who I can have a laugh with as well,  where the hell is my knight In shining armour!..is he stuck in traffic?

You got to hold on to what you've got.

Okay so quick life update. if I can make it quick that is.
Me and Chris have ended our relationship, it was very difficult as it's just so much more than just ending a relationship as we were engaged and living together, this was over 4-5 weeks ago but its just starting to sink in.
There is just so much to it all, that I don't even know where to start with it but I will say this, just because you are going out with someone doesn't mean you have them and you should never stop trying for one another, this really bothers me that these things happen, I've always tried my hardest to take the time to make an effort in the relationship I am in .
I make the effort  with my looks and compliment them , flirt with them understand their needs ..  a relationship should be  filled with love, understanding,  emotional and physical contact I did these things, but there's only a certain amount of time you can throw yourself I someone and get nothing back, it gets a bit embarassing
I don't give up on people straight away, I tried to talk to him  and tell him what's wrong and what we were lacking   I always did that I made sure I'd tell them how I feel  I always stated the problem and wanted to work on it, so why..why is it when I eventually have had enough that I get friends and family tell me that it's was "out the blue" and "oh you's were perfect"
It was only seen that way because I never told people the arguments, and lack of  love i was getting, whats the point? there was no point in tellig people about arguments,  to be honest I didn't even tell my best friend when things were shit because I was embarassed so I can see why she was shocked .. but realising with Chris I wasn't myself I cut off all my friends and family because that was what he was like I sacrificed alot to be with him and this is where it's got me, it trapped me in a relationship, that I was just comfortable in because I didn't want to tell my mum or come home or even know if I could come home I didn't know I was able to.
Don't pass judgement on something you can only see from the outside.
This has been the most crazy month, I knew it wasn't going to be simple but I know other people would be hurt by this news, but if both people arnt happy in the relationship and you've tried to make it work then eventually you just give up. Thinking about it I guess to him he wasn't expecting me to eventually say the words I want to break up, I guess he's  been so use to me saying to him "okay so this isn't working and that isn't working" and him telling me things are going to improve , that he just wasnt expecting it to end all together.
It makes me so mad I don't understand why im not being heard,
We've been through so Much together as well but feelings started to change and disappear the physical part of the relationship was long gone and all that was left was loving feelings you'd feel towards your brother.
If their are any guys out there reading this, please hold onto what you've got.. (sounds like I'm about to sing some bon jovi) and make an effort, same goes to the women out there it's not just one person's job to keep a relationship going you have to work at it together.
