OK I think I need advice about resetting my boundaries here.
STBExH was horrifically EA and VA - gaslighting, financial control, sense of entitlement, cut me off from friends and family. He walked out about 2 years ago- but I think it was a step he took thinking he would walk back in when he wanted and that I would be more cowed than ever.
I have had intensive counselling since then- recognised I was being abused, dysfunctional family of origin etc etc
We have 2 DC who have gone through a lot before and since. I have worked hard to maintain their relationship with their DF- ringing him to arrange access, having him over for birthdays, Cmas etc. Ditto with his parents- his DM rings me to ask for the kids to visit (they live a few doors away).
Over the past few months, I think exMIL thinks that she can regain the lost ground and is starting on her games again. I have a DS whom she adores; we were all out for coffee (her, me, DS and DD) when she starts at the table about DS 'he's wonderful isn't he, such a marvellous child'. Never comments like this about DD.
Today, she rang me to arrange her going to DD's school play. For last few years, I have bought tickets for them and exH- this year, I let Ex know when the play is on and waited to hear from him about if/when he wants tickets. She wants to buy my tickets from me!
I think I am torn between not wanting my children to be abandoned by their father and his parents vs standing up for myself. Any assertiveness is seen as aggressively preventing them seeing them.
