No pregnancy support but expected to give support?😡

So I have an old friend(?) that I used to be really close to. I moved a few cities away and started to become the person I wanted to be. I became more mature and open-minded and stopped judging people for everything. I got a piercing, two tattoos and fell in love. Two years had gone by since I moved away and I got pregnant with my fiancé. Nobody supported me. My family treated me like shit and told me it was "gross" and "disgusting" that I was pregnant and all of my friends stopped talking to me and wouldn't hangout with me anymore. The old friend only responded when I messaged her multiple times and let me come over twice my entire pregnancy. She told me she was excited for me but made up a million excuses every time I wanted to hangout. She also made an excuse not to go to my baby shower so I literally changed the date so she could come and her family could cater my party (they own a restaurant.) She made up more excuses not to show up but said she'd be there...she didn't show up or let me know why. She was dating a girl 3 years younger than her while she was 16-17. She had her first kiss with this girl after dating for nearly two years. The girls parents are extremely religious and did everything in their power to keep them apart. They threatened to call the cops once my friend turned 18 for being a child predator so they split up before her bday. Two weeks later, she started dating some guy she literally just met. She treated me like shit when I told her I lost my virginity and when I got pregnant. A couple months after meeting this guy, she lost her virginity and got pregnant! She just had her first kiss in a two year relationship and just met this guy and is now pregnant..like wtf. And now after just getting a positive test, she has told everyone she's pregnant and expects me to give her advice and be there for her and be happy for her while also acting like she's fucking better than me. She constantly calls and texts me and acts like we're close again and I want to tell her to go fuck herself but I'm too fucking nice to do that to her when I now exactly how it feels. What am I supposed to do? I think she's being a fucking bitch and I think it's ridiculous how she's acting after everything that happened between us. Just needed to vent.😤
