This one is a long one. My ex and I have been together for 10 yrs. We have 6 children between the 2 of us.?

We married in 2003 and have since then splitten up & gotten back together multitudes of times. Everytime we get into an argument he runs off and sticks me with the bills. I'm a stay at home mom. So I struggle until he desides it's time to come back. The first year we were married we split up and he cheated on me with his ex. We got back together and split up & he did it again. We got back together & he was telling me that I was worthless a bad mom, skanky etc. & that noone would ever want me again. All of this almost on a daily basis. Last year we split up & he refused to help with any of the bills & we almost got throwed out of our apt. Central services pd the rent until I found a job. I wound up divorcing him & at the end of our divorce process I cheated on him. A regret I hate myself for it. He sys he cnt live w/what I done even though he did it 1st. My kids want him to come home. He has stuck me w/the bills again and no job. Shld I give up? I KNOW we love each other.
