what would make him my boyfriend ?

3 months ago I had the brilliant idea of signing into Bumble (aka a dating app). I met a couple of guys, but really clicked with one of them. We have been going out on dates together ever since, I've been to his place and he has to mine. We've had sex twice already. Text everyday. He calls me Babe or Baby or something along those lines. I call him Mi Amor (my love) or babe or Mi viejito (my oldie, since he is 42 and I am 21). He has already met my best friend but I haven't met anyone from his side.
