not sure what to think

so now my ex bf wants to talk. a week after the fight, break-up and everything else that happened. he is saying all the right things and i know that he is sincere. he always is. for now. i so want to believe that this time it will stick. i dont believe that people cant change. alcoholics, drug users, abusred people. all have changed to get help, recover, counciling, you name it. i guess all i can do is wait, watch, and make sure he knows that im watching...from a distance.
