Do you think I'm in the right?

See about 8 months ago I had a boyfriend and we broke up in December of last year. He broke up with me because I wouldn't have sex with him (not mentally ready), so already one a** W**** point there. He also made me feel like shit during the relationship saying that I needed to wear make up to make me look more feminine and that I should wear dresses which he knew l didn't like wearing. Anyway a few months later I agreed to be civil with him and he messaged me saying he was going to kill himself because he couldn't get me back, aka mentally blackmailing me. Then after that he told me that my grandad (who was in the hospital at the time, dying as far as we knew) was not that ill and that his grandma who was going in for an operation on her hip was way worse and I was crying and saying all that was wrong with my grandad to him for attention. That's when I finally snapped and I cut all ties with him. I have him blocked on all social medias and I have his number blocked too. Anyway fast forward to a few weeks ago to the point where I bump into him on my way to taking my brother home from school and he tries to talk to me and I just gave one word answers and tried to make it seem like he wasnt wanted there which obviously didn't work because he came home from Spain the other day and dropped off a cheap bracelet and key chain for me, giving them to my dad saying that he was giving them to all his friends. I made it clear that I didn't want anything to do with him and he was calling me his ""friend" I was furious (also the keychain had a K on it which doesnt resemble anything from my name but it does with the first letter of his name)

Anyway a few days ago my friend messaged me asking if I wanted to hang out with him (you should know that he was my first boyfriend back in school when I was like 11 or 12) and I said yes. Then my mum started saying that she will never like him cos he was a little mean to me after we broke up SIX BLOODY YEARS AGO. He has changed and has helped me through a lot of shit. But then my mum has the audacity to turn around and say that if I'm forgiving him then I should forgive my ex (the one in the last chapter I was telling you about) that really pissed me off. Do you think that I am in the right to be pissed or do you think my mum has a point?
