Boyfriend doesn't remember the conversation we had....

I'm pregnant with me and my boyfriend's first baby. My boyfriend is pretty awkward around his parents but they have been very involved. My boyfriend went to hang out with friends last night and came home at 4am completely hammered. He started talking to me all emotional and crying. He was saying how both his parents sexually abused him for years. He was forced to perform oral on his mom when he was 5 and his dad did horrendous things to him. He was crying. Saying he never said anything because it wss his fault and he never told his mom no when he was 5. So that made his dad think he could do it. We've been together for 3 years and he never told any of this. He was so drunk and sad. He pissed our bed that night. Idk if it was from him drinking so much reliving trauma or both. He doesn't remember telling me any of this and I feel we need to talk about it because I don't want those sick fucks around our baby. He's acting like nothing happened and has no idea what he told me.

Edit: Sorry about the confusion between boyfriend and husband. We were engaged at one point and I called him my husband but that kind of fell through so sometimes I forget.
