I spoke to him today, casually, about moving forward. I mentioned dating and things of the kind. He became noticeably jealous. We spent a long time together this afternoon after that, laughing and talking. It was a good time. i think he went to OW's apartment afterward for half an hour or so. I don't know how I'm supposed to survive this.
You need to stop sleeping with him immediately. He's sleeping with her too. That puts you at risk for STDs. This is a health issue and you shouldn't be gambling with your health!
As far as being terrified of him filing, why does that terrify you?
