Should I stay or should I go?

Hello,

My boyfriend of 15 years has made some really bad choices. I feel you are realiable for your own actions, and need to be responsible for them!!! Well in 1997 he left me and didn’t find out all the money he had gotten from his Workmen’s Comp Injury, plus a few more Lawsuites.He left because he didn’t wont me to find out and come back 6 months later wonting to come home. Well I let him not knowing about all this plus going to sleep with his ex-girlfriend. I didn’t find out about all this untill I made him leave two years ago. I had a lump in my breast and it needed to be removed, not knowing if it was cancer or not. I was scared, he said he would be there for me but instead he choose to lie to me and dump me off at the hospital to go see the same ex-girlfriend he sleep with in the past!! He told the nurse to leave a messsge on the answering machine when I would be done. He had a cell phone and didn’t even give them the phone number, or he couldn’t take two minutes out of his time to even call!! I wake up to the nurse asking me if there is someone else who could come and pick me up, as they had left a message over 3 hours ago, and they had not seen or heard from him when he droped me off. Well he comes in right then. We have gotten into pleanty of fights over this and this is why I made him move out, plus on top of that he is working for her brother-in-law that I didn’t know about!! We have been apart for two years and he wont leave me alone and keeps telling me he loves me and misses his family!! We have a 11 year old son together. He has not dated anyone neither have I. I do love him but not sure if I beleive he was ever in love with me!! His ex-girlfriend has always been after him and I feel he should have put a stop to it a long time ago!! I told him he was free he should go see her she has no boyfriend, since he seems to always run to her and has paid $20,000.00 in bills she left behind that he could have gotten back ifhe would have taken her to court!! I think his ego was hurt when she cheated on him, and that has bothered him. He also was injured on the job and I think when he watched his surgery being done because he told the doctors he didn’t wont to be passed out, it left him chemaclly imbalanced. He had crushed his heal when he jumped off a fork lift. He personality and his realationship with me has changed Dramaticly. He is finnaly going to see a Therapist next Tuesday and wonts me to go’ should I? I’m not sure if I can forgive him for what he has done. When he got all that money and came back home and told me he was just getting disability, he actually had checks going over to his moms house for two years I knew nothing about!! Do you think ther is hope or should I just move on?
