I posted this in relationships but didn't get much response so thought other people may have had the same problems in this area. I hope that's ok!
I'm interested to see whether it would be an issue for you if the man you were with has his children on the opposite weekends that you had yours? We've not been together that long so haven't met each other's DC yet. I hadn't really thought about it until now, but would this be a reason for you to reconsider progressing things?
I can't change my weekends as my ex works, and my partner has said he won't ask his ex to swap as he doesn't want to rock the boat (he didn't use those words, but that was the general gist!). As far as I'm aware there is no reason his ex couldn't swap.
Is this just going to be too difficult with all the kids involved?
