I don't really neeed advice so much as an opportunity to vent. exBIL is a truly awful person who has behaved appallingly to everyone, with, obviously SIL taking the brunt of it and their DC suffering as a result too. MIL lives with SIL and her DC.
After exBIL had been absent for a long time, he has recently reappeared. Because SIL cannot accept that he is a truly awful person - she chalks all of his behaviours up to poor mental health and so hates the behaviours but is constantly justifying/excusing them - she doesn't put any boundaries in place and he is allowed to spend time with their DC at her house as his house is, apparently, "not suitable" and for whatever reason, god forbid he should take them out anywhere.
We do not allow our DC to be around him. She had previously accepted this when he was being very aggressive and borderline violent in the past. But now he's back, and while he's as unpleasant and volatile as ever, he's not (yet) being violent or aggressive to that level, so in her head, it's fine for him to be around all the children. We do not feel that way and see his behaviours as harmful. I worry about their children too, but obviously, there is nothign I can do about that.
But we're starting to get pressure. Hints that we're being unreasonable. That if we don't go over there more, MIL is the one who suffers (she won't come to ours as she's disabled and our house is not set up for her and sadly, can't be). Also that we're not being supportive enough of exBIL and his struggles (WTAF?)
It's coming to a head now as we start school again as the DC are old enough to walk over to hers after school and would usually do that regularly. But neither of them want to do it when he is there. DS is older and not scared to stand up for himself which actually worries me MORE because exBIL has form for turning very aggressive on anyone he perceives as beneath him who dares to question him (women, children, and, I suspect, anyone who isn't a white British man. I told you, he's very unpleasant). DD just hates being in his presence.
I'm not going to change anything. I'm going to accept being the bad guy. I know it's going to cause tension between me and DH because he agrees 100% (and is actually even more strict than I am on NC with exBIL) but he is also the one who feels the guilt and sadness with his sister and mother.
So just wanted to come here to scream in a virtual world!!!!! AAAARRRRRRGHHHHHHHHHHHHH!!!!!
