I was friends with a guy when I was younger, in my teens/early twenties, we were very closed and lived together for a while (only ever platonic friendship).
We grew apart as we got older and got partners etc... And there were things about him I wasn't that keen on as we got older so we drifted apart.
At the time, he had a little girl with his then partner. He left her and had a baby with someone else and basically never saw this little girl again. At the time there was some big speech on his social media about how she was better off without him anyway because he'd hurt her Mum and so he was going to move on with his life and let them (little girl and her Mum) get on with theirs as if he didn't exist because she doesn't need him.
At the time the girls Mum made it very clear that this wasn't her doing (I spoke to her occasionally and checked in on her when all this was going on) he just wanted to go off and have his new family and quite honestly from knowing him it didn't surprise me at all and I genuinely believe it to be true (as I say, there were things I started not to like about him).
Anyway, to the point... I deleted him on social media and never spoke to him again. I know a couple of other friends confronted him and he says the same thing 'she doesn't need him, better off without him etc...'. I couldn't stomach seeing all the happy family posts about his new partner and child and how he'd completely just cut off his little girl (deleted her pictures from his profile etc...) so I just deleted him and cut him out, we never actually spoke about it though.
He recently sent me a friend request again and has messaged me asking me why I deleted him and why we don't speak anymore, how am I etc etc...
AIBU to tell him the truth, that I find what he did absolutely disgusting and I don't intend to condone it in any way by being friends with him or do I just ignore?
