Ex boyfriend is mad and is trying to get his “Best friend” to fight me !!!

So hello most of you all know, I was in an abusive relationship! I made it out before it got worse! I’ve been single for about 9 or 10 days now! And Im loving it! Now on the other hand my ex boyfriend hates it!! He’s mad because I left , he’s mad because I want to move on , he told me that if I take him back . He’ll change and won’t be abusive anymore! I told him “NO” When we seperatwd , he told me to move on but I am trying to but he’s the one who wants me back and stuff. He said he will move on too but yet again he keeps On trying to have contact with me. This is so annoying, I blocked his number yesterday and so then he messaged me on Instagram saying “Oh you can post pictures but not answer my text messages” I’m like dude are you serious right now? Like we’re not together. He told me “I’m not his girl so he doesn’t have to answer my text messages back” and ok I know that but he needs to expect the Same from me! So today I found out that since I told him no that we’re not getting back together, now he’s mad about that and now he’s like “Oh I’m gonna get my “best friend” who is a girl to come fight you! I’m like seriously? Just because I don’t wanna get back with you! He’s so wierd and crazy man! He’s 22, I’m 18 but he tells me I’m the one who acts “childish” and acts like “a child” He also told me that another reason why we’re not together is because I don’t go out and go to parties and drink and smoke and I’m like well I’m sorry I don’t do any of that but if I go to a party , he’ll acuse me of cheating and shit. Y’all he’s very insecure asf and only wants to be with me because of my money! I asked him “Why would you lead your “best friend” on To come fight me?” Like what the hell and he said she’s not . We’re just trying to scare you. And so she got my number out of his phone and started texting me! Apparently they tell eachother EVERYTHING. I think this is why she got into the situation. So anyway she started texting me and she was like “ be ready for This ass whopping” and “ you never have to question my loyalty. I’m always there for my ex boyfriend no matter what” and I started thinking in my head “Ok well she should be his gf . Do everything I did for him , give him money and everything” he won’t find anyone else that did all the shit that I did for him! It’s just amazing that he’s doing all this. I don’t think him And his “best friend” who he calls it Are even best friends! I think there more of dating ! She’s claims to always be over his house . I’m just tired of this! Like I’ve been single, I don’t understand why he can’t just leave me alone . I’ve moved on , I don’t know why he can’t move on either. Ladies I need your input please , is this guy crazy? Is him and his “best friend” crazy? And one more thing I live in Maryland and he and his “best friend” lives In Washington , DC. Maryland and DC are an hour apart from eachother, and if you take the train it could be longer, do you think she’s gonna come all the way out here just to fight me then leave? My ex said she’s not , “there just trying to scare me. I need your advice ladies! Thanks! And btw I blocked both of their numbers and sorry it’s so long
