Boyfriends mom didn’t want me to have the baby

(Preface this by saying I am pro-choice)

About a year ago when I found out I was pregnant, my boyfriend and his mom had pretty toxic and horrific reactions to the news. My bf and I had been together for 4 years & talked a lot about having kids. I was heartbroken when his reaction was to terminate the pregnancy because his “family would be so disappointed in him.” When I was 3 weeks pregnant, he and his mom bombarded me on the phone said we were too young (were 25) and broke to have a baby. His mom said I wasn’t a “whole person” yet and couldn’t bring a whole being into the world, stated several times that it would be bad idea, deeply irresponsible, I wouldn’t be able to follow my dreams, blah blah blah etc. I told them my parents were around 23 when they had my brother, she then brought up my dad not being in my life & I said it all happened for a reason and even though it sucked, my family was closer bc of it. She laughed and said I shouldn’t have gotten used to that. After this whole conversation, I started feeling depressed & suicidal. I separately told my boyfriend how I was feeling and made plans to travel back home to be close to my mom (who respected whichever choice I made). Without me knowing, my boyfriend told his mom I was feeling suicidal and they both used this information to further the idea that I shouldn’t have the baby. His mom said I should get back home (6 hrs away) asap and get checked into a mental hospital and then told me to “get help.” She told my boyfriend that I am using this baby as some big sign from the universe (referring to the fact that my brother died in February a year before and my baby’s due date was February). She also said we’d be destroying a life. While otp with my mom, she told her she wouldn’t be babysitting and didn’t have time for that anymore and every mom eventually resents their children to a certain degree. (Yes she said this to my grieving mother) SKIP TO a year later, I have a beautiful baby boy who is SO easy going, chill, sleeps through the night and the best decision I’ve ever made and NOW she not only won’t apologize, but she is upset with me for not allowing her to see the baby right away when I was fighting with my boyfriend. (I was 1 month postpartum). She’s seen him twice now and every time, says something backhanded to cut me down. I let her hold my baby all day (was trying to be understanding & welcoming) but by the end of the day she was asking to be able to watch him ALONE. Without me or my boyfriend. She then walked off with my baby several times after clearly seeing how uncomfortable I was. I told my boyfriend I didn’t feel comfortable with her watching our baby alone or even with him there. Essentially if she’s with my baby then I want to be too. All this to ask… am I being too controlling? I don’t trust her. I don’t want to punish my son by not letting him have a relationship with any of his family so I will always make sure he does but I don’t want to leave him alone with her. Is that wrong? I need feedback because I’m genuinely not sure how to go about this.
