I swear who else can’t stand their SO family?

I’m so irritated and annoyed . I can’t stand my SO family . All his sisters are bitches including his mom . He has the shittiest family on this earth . I’ve been with him 5 fucking years and I NEVER disrespected his mom , nobody in his family . I was the dumb girlfriend who wanted to be liked and wanted to be best friends with his mom but fuck I should have known after all the in laws in the family told me how fucked up this family was . My mother n law has always talked shit about me , my parenting , my family she just hates me I never knew why I guess because I married her youngest and we moved out and started our family . I took away her baby . But I just don’t get how she could hate me if all I’ve ever done is love her son ? Do everything for him ? How could his family talk mad shit about me if I’ve always stayed in my lane . I’ve always kept to myself ? I can’t believe people like this actually exists ? My family loves my SO and has never talked bad about him never disrespects him never does anything but love him ? Sorry ladies but I had to vent .. I’m pregnant with our third and I’m just like ragging with hormones and indefinitely fed up after so many years you’d think people would just grow up .. I feel bad for my SO because his family just pushes me away just to tell him how I hate his family when they’ve always given me a reason to not come around or feel welcomed .. I’m just surprised my family has NEVER made him feel the way his family makes me feel .
