Complicated situation 😞

There’s a lot of thoughts in my head right now. I am in love with another man I’ve known for 10+ years, we always rekindle he knows I have children and I’m in a complicated situation with my Son’s father to where I’m not even sure if I want to live with him given the fact that he still doesn’t have his shit together and we have 2 children. He cheated on me a few months back and now I’m just trying to kind of pretty much start a new happy life. I love the father of my children also, even with all of the ugly shit that has happened but at the same time. I feel like it just won’t be different once again after giving him so many chances…. I don’t know what to do……He says it will be different but I just don’t know what to believe. I’m saving money for just in case, because at this point I just want to make sure the kids and I are good on my end.
