Separated 6 weeks ago, stbexh living with his parents.
His shift patterns mean that he only has 1 in 3 full weekends off, so he's had 2 such weekends since the split. Has he spent those weekends with his children? Oh no, he has spent them both "reconnecting" with an ex from 30 years ago, and hundreds of miles away!
I initiated the separation and I am more than happy for him to move on, I just think it's selfish of him to prioritise getting his leg over, over seeing his kids, especially at such an early stage of the separation.
Since we split, he's done no overnights with the kids, and also refuses to commit to a regular schedule of contact because of his shifts 
So AIBU - no he's not a selfish twat and he's entitled to a life, even though I don't get to have one (and can't think of anything worse than going back into the dating world)
Or is he BU - the kids come first and everything else should work around his contact time, not squeezing the kids in when it suits him
