DSis had a baby with a one night stand, they had been friends a long time but just slept together the once.
When DN came along the Bio dad and her raised as co parents, he got her a house (she was homeless) and he stayed in the spare room, did the night feeds etc.
Eventually he moved out but continued to see DN 3/4 times a week and had him every other weekend.
Then DSis got a new fella, moved him in within 1 Month of knowing him, made DN call him dad and cut off nephews real dad completely, not allowing him to see his son etc. She told him he wasn't cut out for being a dad and that DN has a better man now who would take better care of him than he could. (He fought this for 2 months then gave up - so he's a piece of shit himself for stopping trying in the first place - however he was only 22)
Anyway he keeps asking DSis now to see his son for the last 6 months or so, says he wants to take her to court etc. nephew is now 2y/o DSis says no and that her new bf will be adopting nephew eventually and dad needs to get lost basically.
The dad pays her phone bills, Sky TV bills, council tax and pays £500pm to her (he works a min wage job in retail) this was done via court he just pays what she's asked for. For what it's worth he was amazing with DN when he was in the picture, my sister had PND (undiagnosed) and didn't really bond with nephew and he really did step up. Sister also had a bad relationship with money so he ensured weekly food deliveries, clothes etc were made.
Now AIBU to be telling her she cannot keep accepting his money but deny him the right to see his child just because she wants the new man to be the dad? That if she is going to completely push him out of the picture, her new man can pay for their bills himself (she does also work)
I feel I need to support my sister but I look at my DH and think of the heartbreak it would cause him to be separated from our children and I hate it - she can't expect the bio dad to fund her son and not give him a chance to bond with him.
hard hat at the ready to be told IABU
