Where is the ‘abandonment’?? Simply living in another home isn’t abandoning your parents (then aren’t daughters abandoning their parents as well )
A mother doesn’t have the right to expect her son NOT to sleep with his wife.. That is bizarre and overstepping boundaries.. A woman should be sleeping in a room with her own husband, not her grown son..
ANY doctor here would say it’s understandable if the OP is depressed as well.. What her MIL is doing is not normal, it’s obsessional and we can’t control what others do but we can speak out or how will there ever be any chance of change?? Just ignoring things for years on end can and does cause depression.. It is NOT healthy or constructive..
The OP being ‘bothered’ about how the other girls are treated shows she’s a good person and has empathy.. A quality some ppl on GS seem to need to learn.. I wonder how they’d like to be on the receiving end of bad treatment whilst others turn a blind eye..
