[quote icecreamgirl94]@loubieloo4 thank you. I really don’t know where this leaves my relationship with DM to be honest, I think I’m sort of waiting to see if things drastically change once DSis’s baby is here and hoping that they do because I don’t want to fully lose contact with DM but I think fully rejecting DSis would give me no choice. It’s hard because DP and I are so excited for this baby and can’t wait to meet him/her but we feel guilty feeling like this around DSis.[/quote]
This is a terrible, mean thing for you to do to your own mother. So, unless she does what you dictate, by taking back your sister and supporting her financially, practically and emotionally in this pregnancy and with a baby, toddler etc, you will “fully” lose contact with your own mother? That is very manipulative, and nasty.
If you and your father and all this extended family are so supportive of this baby, how about your father finds somewhere else to live that’s two bedroom so he can do the grunt work of supporting his daughter with this new baby. It’s so nice that he’s so supportive of her and willing to “help”, but he gets to opt out of all care and responsibility by every so unfortunately not having practical housing options. How convenient for him.
Or, she can live with you and your partner indefinitely. It will put a great deal of stress on your relationship with your partner, and your finances, but if you are this supportive you will manage it.
Your sister by all accounts can’t organise her way out of a cardboard box, and can’t manage her own relationships with people without you or your father and extended family involvement, yet is apparently mature enough to parent a newborn ... it’s clearly inconvenient for everyone else that your mother has put her foot down about this because everyone else has plenty of opinions and decisions they’ve made as long as they don’t have to help out (at all, or very much).
So what of the baby’s father and his parents (if he’s as useless as your sister?). Why can’t they step up with practical and emotional support that does not involve dumping the lot on your mother?
I do think you did a good, generous thing taking in your sister. But she must learn to stand on her own feet and take responsibility for the choices she’s made and the life she now has to leave. And you need to stop dictating how your own mother lives her life.
