I know this person has a personality disorder, but which one is it?

I met this girl online, she asked me after two conversations if I want to be best friends with her. It caught be off guard that a 36 year old woman is asking me if we can be best friends after only talking on the phone once. I’m also going through a difficult time and she immediately offered to help me although I should be flattered, I also see it as a red flag. If I was a bad person I could take advantage but I don’t. My mom is a narcissist who pretended to care and had me travel to another state just to tell me I couldn’t live with her after saying I could. I know I have mommy issues so I’m naturally skeptical of women who are nice to me or overly nice. It’s the ones with those sweet sounding voices and they cling to you quickly that tend to have something up their sleeve. Maybe it’s just me ? I want to meet normal people but I keep meeting these weirdos that want to be best friends In 2 days, want to take all my time and space and text or call me all day. I would know because I met two people off the peanut app and 1 calls me every hour and questions me when I don’t pick up the phone or have other plans. I set my boundaries of course but she didn’t like it. Then the other is really sweet to the point it’s kinda creepy and she said I can live with her, offers me money on cash app and ask me to be her bestfriend in 2 days. I can’t make this up and it’s making me realise this country has a serious mental health crisis.
