Guy problems.

I started talking to this guy in the beginning of January and things were going really good. We went on a couple of dates and we both seemed to really like eachother. I’m 21 and he’s 34. I’ve spent the night at his house and we even have had sex. I asked him what were we the other day because I’m confused and he said “not bf and gf I want to take things slow” but how is spending the night everytime we’re together and having sex taking things “slow”? In person he’s really nice and sweet and over text he’s super dry. I’ve been feeling like he’s trying to distance himself from me though. I’m nervous. What do you guys think? I already caught feelings. I’m super sad.
