Is this loveboming?

My friend recently started dating this guy and we are all very happy for her however there are some concerns I have. Some background: she is anxious attachment, falls pretty easily. They met on a dating app and jsut started dating a week ago. She texts him nonstop and talks about him a lot which Im glad she’s happy but I’m starting to see some potential red flags. He told her he’s already saving up money to buy her a ring and that he’s obsessed with her. He texts her nonstop about her looks and how much he cares about her and can’t see himself with anyone else. About a few weeks ago he gave her a nasty uti and horrible sickness. I don't know if that also means anything I just thought it was strange. He admitting to treating girls in the past like shit because they quote “seemed more attracted to him then he was to them” and didn’t see them as wife material. He also openly admitted that his exes are crazy and stupid. If she doesn’t respond fast he gets upset and stressed out. He tells her that he doesn’t want her to not spend times with friends/families at least but I can’t really tell what he’s like yet I haven’t met him. They discuss everything and anything all the time and it just seems too fast in my opinion. Anyone experience anything similar or have any idea if this is normal. I jsut don’t want her to get hurt.
