What do I do? I am very confused!

Ok here goes~I met my boyfriend on facebook..we talked for a very long time then we met a few times and he moved in. The guy was in a very bad car accident when he was 13 so he drags his left leg and talks like he mumbles and his left arm and hand are very week..When I first met him I had just had a divorce shortly before that.

Now besides the physical features he is a very hard worker. He wants to take care of me forever. He buys me whatever I want. Now..I NEVER ask him for anything he just does it. I always refuse but he still does it. I am a very independant woman. I guess that would come from previous bad relationships. I am sooo not sure that I even want a relationship. I seem to always pick the bad guys and now I ended up with a good guy I am pushing him away..well trying..he won't take it.

I have a 5 year old son, a 3 year old daughter and a 16 year old boy..they all aren't too crazy about him and I think it's because he has physical problems.

I don't know what to do!!! I'm so confused!
