Long story short!!
I separated from my husband last year. My sil (exh’s) sister had a dad and she has found our separation really hard to come to terms with (she is 10) none of friends parents are separated, so this has blown her mind I suppose with how relationships can change. She is now an anxious mess about the possibility of her own parents separating. Dsil is at the end of her thether and is worried. She blames me (because I left the marriage) and she has messaged me saying dn needs therapy of some sort and I should be paying as it’s all my fault! I gave my own dc to look after, I have money for their therapy as and when they need it (not needed as of yet) Aibu to think DN’s struggle of not my responsibility? Please go easy.
