Does he want to get back together?

I’d been living with my boyfriend for about 6 months, dating for about a year. He broke up with me a few weeks ago and said he just doesn’t know how he feels or what he wants anymore (he’s only 19 and I’m 18 so I get that it’s scary the thought of being with this person forever). He said he still wants to be friends because I’m his best friend still, since breaking up he has still be messaging me basically every day just talking and multiple times has asked me to stay over... do you think there’s a chance he’s regrets breaking up? What should I do?
