So my boyfriend and I have been ttc for over a year now. Yesterday we got into an argument because he has two kids from a previous relationship and he said if his kids were to ask to have their younger sibling to sleep over that it’s fine.. I told him straight up. I have no problem with them wanting to see their sibling everyday I will make that happen but as for sleeping over his ex wife’s house that doesn’t sit right with me. First she has nothing to do with my kid but her kids do and I just think she won’t treat my child nice being as it’s my child and she thinks me and her baby dad cheated on her before they broke up which isn’t true at all. I spoke to him a month after they broke up and he moved out. My boyfriend says she won’t do anything but I just don’t feel comfortable with my child sleeping over her house. He says well she lets her kids be with me. I’m like well that’s because me and you live together and have been together for three years and you love with me so the kids come to see you on your days. I might be overreacting but I just don’t want my child spending a night with her
