How do I 20/F go about things with my baby’s father 27/M?

I 20/F find out I'm currently 7 weeks pregnant by my baby’s father 27/M. We met at work 2 years ago but never interacted more than just co-workers jump to April 2025 we don't work together anymore, we started talking and hooking up, I just got out of a year-long relationship 2 months prior in February and he broke up with his ex girlfriend whom he was with for 3 years around the same time. In the beginning, I really liked him and wanted his attention and wanted to try and form a relationship with him but lost that interest after a month when he became inconsistent he'd ghost for sometimes up to 2 weeks then come back like nothing but it didn't bother me because after the first time at that point I wasn't looking for anything more than hooking up with him and that's as far as our relationship went then in the beginning of July I missed my period so I went to the hospital and took a pregnancy test and it came back positive and I was 5 weeks along by then I told him the same day I found out and since then he's done a complete 180°. he's been checking on me every day asking how I'm feeling if I need anything and at night he’ll come over and just stay with me and act like we’re in a relationship basically he's also started saying I love you and calling me baby I haven't said anything but deep down I know if I wasn't pregnant he wouldn't be doing this so I'm keeping my feelings and emotions neutral but i’m wondering how I should handle this?
