Cyber bullying and harassment 2.

Why do I feel like crap for trying to be nice to my step sons mother. Not even nice cordial, because I hated her so much because she put me and my kids through hell and I matured from hate and I just don’t like her as a female and I can’t respect her but I am a cordial person and I love my stepson dearly. I posted before about cyber bullying and harassment on here. I took the time out like I always do to think of the mom and her other child and she is due soon, Christmas i went out and got gifts for her oldest and for her birthday I took the time out and surprised her with cupcakes and balloons for my step son and for him to see that there is no hate in my heart and I am a nice person. He knows that but mom try’s to put a image on me. No one has said anything to me but this time couple weeks ago I made some baby onesies with cute phrases for the mom and sent him home with them to show her and he helped me make him I love keeping him involved but instead she has her family bash me online and call me crazy and etc I need to leave them alone, I look like certain things and I I’m gay and etc and then went and violated me on my fb page and tagged me and these chicks work at a doctors office and their bosses are on there. How do they just allow it? I get with covid they are out of work and bored. And I know they are immature and belittle people but why do I feel like shit for doing things out of the kindness of my heart ( Sorry for the vent, I have no one to talk to)
