My Mother has apparently been seeing a psychologist who told her I have abandaoned her!!!!?

So sorry you are going through all of this. Life is difficult enough with your own little family, add a sick mother-in-law and grandchild/ren she is missing and of course your mother is jealous of this. Unfortunately, she doesn't appreciate you are doing the best you can and it isn't any fault of yours. You deserve to live your life in peace and she is doing this to make you feel guilty, and of course being pregnant and caring for a sick relative and a small baby is overwhelming. Your husband is very sweet to suggest a joint session with her psychologist. The real issue is you have grown up and your mother can't handle it. Good luck with this but please don't feel responsible for your mothers feelings. You have not abandoned her you just live farther away. Maybe she could come for a visit when the new baby comes.
