Welcome to being a man, my friend...
Honestly tho. All you can do is keep trying. This sounds like its upto her. Im going to try to stay on nuetral ground here, because I dont like being the bad guy.
I both of you need to just sit down, and start a square1. And discuss everything. Likes and dislikes about eachother, without being nasty about it. This takes a little effort on both of your parts.
Neither one of you can change eachother. You can only change yourself. Life is a one man game, everything else are obsticles.
