AITA for pushing my friend away since I’ve gotten a boyfriend?

Backstory about me, I just recently graduated college I’m 22. I’ve been dating this guy for around 7 months and everything has been going great, even though we’ve been dating for only 7 months I’ve known him for years. He’s a few years older then me but we have a perfect relationship. No arguments, everything is just always smooth and he makes me happy. My friend, let’s call her Z is single and she lives a few towns over. We always hang out here and there but for the past few months I haven’t been really hanging with anybody but my boyfriend due to the fact I moved and we’re busy balancing the dynamics of now just living together

Z called me a few days ago and basically went off on me and started calling me a “bitch” and that “I cut her off for my boyfriend” when it was nothing like that — I just haven’t been consistent with replying and checking up on her but I’ve always made sure to text her and call her once in a while. I’ve just been busy. I tried to defend myself but she hung up and blocked me. Now that we had that fight — it got me thinking, I really never had a female friend be a good friend to me. In fact, in the past I’ve had several friends lie to me, hurt me, and steal from me. One female friend even physically assaulted me to the point I had a black eye after we had got drunk and she started an fight with me.

I’m lowkey traumatized from having girlfriends, and I’ve only had a good 2 female friends in my life that haven’t wronged me. I tend to get hurt with these friendships too because I come attached to my female friend and really care about them whole time they don’t care about Me. Now that I have a boyfriend he’s honestly my best friend and I feel like even aside from the relationship our friendship is so strong we’ll always care about each other. Even though I’ve moved, I haven’t made it a point to reach out to other women or try forming friends because I’m honestly scared and I feel like the 2 friends I have now plus my sister and boyfriend are all the friends I need. Is that so wrong?
