So my husband and I have been together going on five years and married going on three years. My husband has two kids who he thinks may not be his but has always cared for them. Recently we got custody of the children due to the mother being on drugs and CPS removing them. We used to have trouble in the past being that the mother of the children would always have something to say about my husband and when we first got custody of the kids she made a statement to the case worker saying I did not have custody of my kids because I was allowing my dad to molest my oldest daughter, which is a disgusting thing to say. My husband was angry and I was livid and hurt being that I was a victim of abuse at a early age of 2 all the way until I was 6. Anyways we have a restraining order now and she can talk to them on Fridays for a hour. She just talks about herself and her drug court and her recent pregnancy that is 8 pregnancies total with her. Well she then said that three years ago my husband went over there and slept with her and that one of her other kids might be his. My heart was broken I mean I trust my husband but that's enough. I can't even be around my husband without being emotional. He says that never happened but it's still in my mind. I just want this to over with. He recently was looking at houses and I told him I do not want to buy a house until we get DNA test on both children. I know it's harsh but I don't know what other option I have besides leaving and having my children grow up without a father. Idk how else to feel or what else to do...
