Sis I have wanted to post but honestly I have no idea what to say. My first reaction is to say, "He is not making enough effort cut your losses." But I don't know that I could take my own advice and I don't want to be a hypocrite...
I agree with what John said, either he doesn't want it bad enough or he is happy with the (little) relationship that you have now. I wish I had a suggestion to help here but I don't. I just know that if you have to pick him up on your back and carry him where you want him to be, it won't work. And you already know that yourself. Crap!
