Not an AIBU as such, more of a "am I overstepping/getting over involved?" - as I'm prone to doing so.
Background: SIL died a few years ago. I was very close with SIL before she died. I saw quite a bit of her family over the years. SIL never had a great relationship with her Mum - it went from strained to almost friendly by the time of SILs death. We supported each other a bit after SIL died and exchange xmas cards but little more now. I'm still in close contact with her brother. SILs Mum works in a nursery. SIL had a work colleague she was very close to, thought of him as like a son.
A few months ago, SILs brother told me that previously mentioned work colleague had been arrested on accusation of being a pedophile. Now, he has been charged with over 200 cases. At first it looked to be all teens (13-15) but now it seems there are cases of younger children too. SILs Mum is having a very difficult time with it all. According to SILs brother she's crying all the time, not eating and feels devastated and betrayed. She's been refusing help/support from everyone as far as SILs brother can tell.
I want to write to her to express that I have an understanding of how difficult it must be for her (my uncle was accused, albeit then acquitted of similar crimes when I was young), am happy to offer her my support and offer some advice.
The issue: I am renowned for getting overly emotionally invested in other people's problems. It has caused me some mental health issues in the past as I often neglect myself/my needs in order to support the other person. I have a compulsive need to get involved and try to help people. I really don't want to overstep the boundary though. I hope this makes sense. NC for this.
I suppose this is more of a WWYD? Apologies.
