Pregnant with toxic family

Me

My parents and I stopped talking at the start of my second trimester when we told them the news of our pregnancy. The reason being is because they yelled at me for leaving their house when my older sister came. We don’t speak because she’s bossy and controlling and said hurtful things to me in the past about not being pregnant. When she came that day her kids who love me, ran up to me to give me hugs and she yelled at them saying get away from me. Some mature person right? Fast forward to now 8 months pregnant. My mom texts me saying Noah (sisters son) misses me and he loves he aunt. I said I’m sorry I’m not hiding to talk to their kids they nade it clear they want me to have nothing to do w them. My mom never responded to that. My niece and nephew love me I spent so much time with them playing buying them toys all while my sister disrespected me. I made up my mind that I needed to put an end to the one sidedness especially now that I’m pregnant. So for thanksgiving my mom texts hi I made food lmk if you want me to drop it off. I didn’t respond to her she shows up today at my doorstep and we had it out. I told her she hasn’t been there for me and to leave us alone. Anywho I made it very clear that I did not want to announce my pregnancy to anyone else in the beginning and I find out that she told other people even tho I told her not to. I’m very angry bc I wanted the good news to come from me, after all it is MY pregnancy. My mom telling ppl and not even there for me. So now I feel forced to announce it on social media. Need advice please. My husband is an angel and has been the one and only support I have had. Only his mom knows my grandma one aunt and cousin. No one else has ever reached out to ask me how I’m doing since. I really decided it’s time I cut them out my life for good. Btw I do have a therapist and she supports that given how toxic they have been to me all my life
