Lost In Love

So, there’s this guy (we work together) I’ve been hanging out with every night after we get off. We established we were both sexually attracted to one another so occasionally we act on it. Well, he’s been acting different lately. He called his place home (for me), he cuddles me when I’m sleep sometimes. He pretty much does what a boyfriend does except kiss me and we usually never text because we are with each other 24/7. But I think I’m catching feelings and he’s leaving in 6 months. What do I do? Anybody have advice? Should I stop what’s going on and stay friends? I feel like we’ve gotten so close and have so much in common 😭
