After a long marriage I am back on the dating market, now mid-40s. I started talking to this man the same age as me about 6 weeks ago. We live near each other but he has been away until last week. Anyways, we had great chemistry over chat/video calls whilst he was away and it was even better when we met last week. We have basically been inseperable since. We have lots of fun, sex is great, we have the same interests, the same taste is music, food, films etc. I find him really attractive and fun and he says he feels the same about me. He says he wants a serious realationship etc. All good so far.
My issue is his past. He has a young child who lives abroad with the mother who he goes and sees for 3-4 weeks at a time 3-4 times a year. They broke up a year ago and he says he finds her really annoying and he's not attracted to her physically. Problem is that they have always had sex when he goes and sees them in this last year. He says I shouldn't be concerned about that because he has been single but he won't do it now that he's met me. She and the child is coming to see him in a month and half and they are all staying in a third country together (where I won't be) and I feel really unsure what to make of that. He said he's going to tell her that he's met me but that obviously won't stop them from having sex.
I asked him how long he's gone without having sex in the last year and he said, maybe a month. In the 6 weeks that we have been talking he has had sex with two other women. I don't expect full committment before meeting someone so I can't really say that he's done anything wrong I guess, but am I strange for feeling a little bit grossed out about it? He says I'm being insecure when I ask about it and that what he's doing is normal. I just don't think I can ever feel relaxed about him spending so much time with the mother of his child who he also occasionally sleeps with even though he's not attracted to her and finds her annoying. If that was true why would he do it?
