sry but mrromantic dude he can lie he can tell her what she wants to hear if he istryin to get back with her and she said e care more about himself he is gointo le to get what he wants

This sounds like me and boyfriend when we first started dating.
He had not had a girlfriend for like 2 years because he still liked his ex.
and i felt the same way that you do right now. It broke my heart everyday to think that im with someone that still likes someone else but we talked about what was going to happen if we didnt sit down and talk about it.
Ask him why he is in the relationship, tell him that he needs to get his love life strait or your gone.
me and my boyfriend have been together for 2 years since we had that talk i trust him and i dont worry about her.
And as for you you sounds like a normal girl that is falling for a boy.
i still act the same way around my bf.
i still want to call him more then i already do and text him more then i should.
and the reason i he doesnt care is because you have had these other men(or boys) fall for you so fast your just used to it.
If this is the real thing then its not gonna be like that.its gonna be a big challenge.
