DBro and SIL are in the midst of a very very bitter divorce.
DBro is StepD to my 2 neices (their BirthDad is not in picture - DBro has been since youngest was 6)
I got on very very well with (ex)SIL (we lived close to them while they where married)
My DBro is well - not a very nice bloke - manipulative,had problems a few years ago with booze, generally an angry man etc (without going into it there is stuff in our childhood -not a excuse but a part explanation as to why over the years I have put up with him to some degree)
DBro is not and said he will not be involved with 2 DN and has moved about 4 hrs away, got new flat etc.
On phone to DBro tonight (to make sure he is alright - I feel like I should as no one else will - we are all each other have famiy wise) he shouted down the phone saying that I should have nothing to do with that 'Fucking dirty bitch or her fucking bitches of daughters'
Now I am glad that he is having nothing to do with DN anymore. but exSIL and I still get on well - we are friends. Her DDs consider and call me and DH aunt and uncle and are very excited to have a new (and the first one) cousin. (we still see each other as live close etc)
But as exSIL is cutting all ties with DBro AIBU to keep in contact with her and DN especially as I will not cut my ties with my brother completely.
Is it fair on DN to still be aunt and uncle and have cousins but yet their StepDad doesn't want anything to do with them? (they are 12 and 14)
I know I could bring this up with exSIL but with all the shit she is going though from DBro I don't want to bring more stuff for her to think about.
So thought I'd get your opinion
