what to do in this situation?

I wouldn't know what to think about that. If my boyfriend said something like that to me I would be asking a lot of questions. It already feels bad enough sometimes feeling like second, I know u know what I mean. Y'all have a new life together and have been together for 6 years, the only thing I could think of is maybe he feels his life would have been better bc he would have got to be there when his kids grew up, like day in and day out through it all instead of being a part time dad. So it could have to do with his kids, his old house, and his life I'm general. I don't think it necessarily means he messes being with her over u. There was 14 years of loneliness he had to deal with before he met u, that's a pretty long time to be alone, so maybe he is talking about all that wasted time before he found u. Men don't always think before they speak so maybe he was talking about having a wife and a family then one day bam divorce and u spend 14 years alone until u finally meet someone who u love and makes u happy. So what he said might just be his residual feelings for when he spent 14 years alone sad and depressed, had he met u sooner maybe his life wouldn't have been so miserable and lonely. Sometimes my bf makes comments along these lines and it makes me sad to think he might even have one care for his ex wife after what she did to him, they still talk and see each other sometimes bc they have a 9 year old daughter it gets tough for me, I already had two kids with someone else so he doesn't want anymore kids he feels like with 3 kids total our plate is already full, so knowing I'll nvr have a kid with him is tough for me to swallow. It hurts sometimes just knowing he shares something special like that with another woman. Plus she doesn't let us take her anywhere so it makes it even harder. So I think it's some what normal to feel like ur bfs heart is some where else when he has been married before and has a kid with someone who is not u. My advice to you is to talk to him about how that comment made u feel, that way ur not dwelling on it. Don't come at him rude or anything just let him know it made u feel like u weren't as important or that he would be happier with her. It's better for u know know how he really meant it now before u marry him. I have nvr been married before and I don't intend on ever being divorced so I am making sure I am really the love of my boyfriends life before we get married bc nobody wants to be second best or a replacement for the woman they lost. Good luck and I hope this helps

Talk to him an ask him what he meant. His kids must be grown up now if he has been divorced for 20 years so he doesn't need to keep in touch for them, so ask him to be honest about his feelings for his ex-wife. Six years is a long time to be engaged, so ask him if he wants to marry you and settle things once an for all.
