My DP, baby daddy, has an ex gf. nothing wrong with that you think. i quite agree. can't be helped, he'd probably be shit at sex otherwise.
they were together for about ~2 years, did live together, split up 2-3 years ago. i believe she wanted a baby and he didn't (heard from him so ¯(ツ)/¯) but it wasn't a ~major~ showdown at the time, I don't think, it just wasn't right.. she and he don't have any ongoing contact and haven't since they split up.
anyway, that was quite some time ago. i couldn't give a monkeys and do not feel threatened by her in the slightest.
his family and she however, are fuckin' all over each other. on facebook and just last week MIL went for a day out with her in [town where she lives] which is quite a way away. they also often discuss her amongst themselves whilst we are having family meals e.g "lol must tell [long forgotten ex]". they (mainly she tbf) post all these ~throwback pics with but everyone's liking and whatever else FB people do. my bf has apparently expressed irritation at this but they don't seem to care what he thinks.
look, it's none of my business, aware, I just think it's a bit disloyal. my family LOVED my ex bf and vice versa, but when split up, we all peacefully parted ways.
they are what they are, and we have quite different views on a lot of things... i'll probably never be compliant enough to get the full integration but i'll keep freedom of thought thanks.
I rarely use my fb but nonetheless all this reminiscing of the good old days is steaming my clams... would I be unreasonable if I quietly defriended the lot of them, so I wasn't tempted to get myself all blustery about how confusing I find their family loyalties? it wouldn't go unnoticed but i would rather not waste my energy on getting all
about them when they are essentially practically another species to me and my family.
