So FS: have you still not told your mum that you are separated? In that case we have even more in common than I thought, lol. Still not told anyone in my family. Though I will when we finally have the D conversation. Not sure what else I can tell my family, it will be a difficult conversation.
Your H sounds very much like mine in a lot of ways. Not wanting to be part of a family towards the end. Wanting independence. Then realising what he lost but not being able to go back on things maybe. Not willing to put the hard work in for reconciliation. And also the always being about him bit. That's what one of my best friends said 'it's always been all about him, hasn't it?' and that was true.
I really identify with the feelings of loss when H takes the kids away. Important to acknowledge it, move on, book something to keep yourself busy, maybe even enjoy the space and time to yourself. H is taking the kids away next week for about 10 days, I was looking forward to spending time with my new man but that is a bit rocky right now so who knows. I feel ok either way, and have the wherewithal to organise plenty of stuff to keep myself busy if I need to.

I don't think you're doing online dating wrong, it's just a matter of luck and a numbers game. Keep on going, have some fun and keep an open mind smile
