I recently blocked someone on all social media because our friendship was making me very upset. This person is also friends with my mother, my mother is who introduced us. I felt like our friendship was mostly just me giving this person money and gifts and them never even making it a priority to not leave me on read. She would never pay me back, and while I don't hound my friends for money I've lent them it really upsets me when she just always asks for more and I never see any of it, or I buy food for her kids etc and she doesn't pay me back, she would flake on me constantly or show up hours late or not at all and then when I tried to express how this upset me she victimized herself and got mad at me. 
I told my mother I blocked her and I want to not have a friendship with her at least right now, and today my mother decided to tell me about how she texted her how she loves and misses me and then made me text her back from her phone because she's driving even though I expressed that being forced to talk to her, especially pretending to be my mom, made me super uncomfortable 
So now I just feel guilty and I'm going to end up unblocking this person because I cannot tolerate guilt and I'm angry with my mother for insisting I text her and not respecting my boundaries at all. I'm stuck in the car with my mom for a while still and I just want to cry I don't want to be near her at all.
