20 weeks pregnant and baby daddy and his mom are making me miserable🤕

Me and my bd were dating for a month when I missed my period and found out I was pregnant. He was excited, told all of his friends and family, came to the first few dr appts and ultrasounds. He was being great. His mom was a little bitch from the start. She only complained ab my insurance needing to come through and didn’t want me going to dr appts bc she didn’t want her son paying for them. (She’s a control freak over him. He’s 22 and still lives with her. He’s also stuck up her ass 24/7 vice versa) she was never positive. Little did I know the whole time she was talking crap about me behind my back to my bd and telling him the baby wasn’t his more than likely. I could DEFINITELY tell he started treating me different and was really shady and didn’t want me talking about the baby. And then he just randomly broke up with me 2 months ago and said he wants a dna test. Well him and his mom want stop ab the dna test, his mom even met up w my mom at the park and told her that wasn’t her grand baby until she gets a dna test. So I told her and my bd to pay for one and we can go get a non invasive prenatal dna test done as soon as next week. I had it all set up. All they had to do was call back and pay. Long story short they just keep putting off the dna test and won’t call. So I just blocked them both... what should I do?! They’re just soooo wishy washy and stressing me out for NO reason. They’re just drama starters.

This is LONG & him and his mom are confusing the fuck outta me. They’re saying there’s a rumor I was sleeping with a guy before him. But can’t tell me “what guy” and I think they’re just lying so they don’t have to be involved with anything.Bc he’s been the only guy I’ve had sex with since I was 16 weeks pregnant with my first son. I just blocked them bc it’s just too much irrelevant drama. What should I do??
