Should i try and keep working on my relationship or should I just leave it alone and move on with my life?

My bf and I have only been together 3 months. Within that time he went ot rehab for alcoholism and i took care of his two kids and my five year old. He just cam home last wk and ever since he's been distant and not very attentive to me. He said hes just trying to get his life in order but I feel like he's just trying to push me out. I mean id oubt ne other woman would do the same for a 37 year old they've barely been with. I feel like he doesn't care and Im at a loss. Im trying to act like I dont care but it gets me upset that he doesn't do the things he use to do. Should I stay and wait to c what happens? Or should I cut ky losses and walk away? Im only 24.. but i really care about him. Please help!!!!
