The other night exh stayed for dinner after dropping the kids back as we had to sort a few things out about our split/kids in care etc. The kids were worn out and went to bed and one thing lead to another and I ending up sleeping with him I don't know how it happened, we have been apart for over a year and I don't have any feelings left for him at all, especially after how he has been to me. The sex wasn't bad, it was just familiar and awkward afterwards. I made him leave straight away and now I feel really bad about it. I wish it hadn't happened. At least he hasn't texted me since (he wouldn't normally anyway), i just hope he's not going around telling people. I feel really weird about it. I don't know how it even happened.I haven't told anyone because I feel awful about it, at least here I can get it off my chest. I just don't want anyone to know but so I don't even want to talk to my friends about it.
