So after 10 years together, partner always pushing for a baby we finally agreed and I am 5 months pregnant. A week ago I stumbled upon messages from a woman we both work with, they were telling each other they loved each other and all the rest of the crp. I confronted him and he said he never told her that and the message were being passed on to him to try and catch out someone at work. 2 days later he admitted it. But denied the love thing. After a talk with a third party to be unbiased he admitted that night that he did say it. He sticks to the fact that he didn't mean anything by it, she would just be saying nice things and it made him feel good. The funniest bit is, this person spilt my best friend and her partner up with a similar situation. I listened to the messages she had found and they sounded very similar, she would say she wasn't happy with her husband and that my partner was different and really nice, how he looked good after losing weight... this was the same rubbish she was saying to my friends partner. I would like to say that the relationship between us was faultless and happy but it hasn't been for a while. I have pulled away altogether. We still had sex but there was no intimacy or affection. He's mentioned this a couple of times over the last year, feeling unloved and no affection, but I didn't see the problem. But there have been times where I have walked away from a cuddle and turned my head from a kiss on nearly every occasion. Almost like two stangers living together.This is I think where he got sucked in by someone blowing smoke up his ase and why he said it felt nice to have someone saying nice things to him and paying him attention. He says there's nothing there. And he's never met her and it was just stupid texts over a week or 2 that were mainly when he was very drunk, which he has been drinking alot more these last few weeks. I've told him he needs to get tested regardless if he met her or not, for my peace of mind. I just don't know if I should stay and accept responsibility for pushing him away or walk away before baby is born knowing I can't trust him.
