SOS...mixed feelings!

I’ve been hooking up/talking to this guy for 3 months now. We hang out at least a few days every week, I’ve met all his friends, I’ve gone on a trip with them, he’s told me something very personal. We also work together (I don’t need to hear how it’s a bad idea). After work last week, he told me he thinks we should hang out less. I asked him why and he said he let me in too fast and he doesn’t do that with just any girl. He said he has to think of it, which I took as he’s trying to see if he truly wants to cont.

Anyways, a few days ago we worked together on the same shift. I thought he wouldn’t talk to me but he did, and was very flirty. We ended up hanging out every day since. We’ve gone out places alone and with friends. Yesterday we were hanging with his friend and they were talking about how relationships make you gain weight. He said something like “yeah relationships usually make you gain weight because the girl is fat and wants you to go out to eat everywhere” (just joking). He quickly turned to me and hugged me and said “but not you, you’re skinny”. I was surprised because of what he implied. Idk if he meant it that way but I was shocked. I’ve also noticed he kisses me hello and bye now. The other day I asked him why he told me all of that stuff last week and now he’s doing all this and he said he’s just going with the flow. I took this as he has feelings towards me and wants to be with me and is just letting it be now ? Idk what to think! Opinions ????
