Like the others have said, with different words: what is there is there, and what is not there, is not there. You cannot change , or force, or rush people in any way.
Let it go and concentrate on YOU. What kind of boyfriend do you want? I think you want the kind who WANTS to come to your party, the kind who WANTS to talk about marriage.
And once you let go of your fixation that it has to be him, you will meet a person just like that. It doesn't even matter if you hit him up or not. I wouldn't, but even if you do, you'll have to sooner or later focus on YOU and what YOU want, not who exactly is going to give it to you, or when it will exactly come.

Sounds like something not worth fighting for. Be patient and let him do what he wants, if he comes back then maybe both of you can work things out. If he doesn't - well, then there are plenty of others guys that will treat you better and not cause drama. :)
