Should I let myself get too attached to someone who may only want casual sex?

For reference, we work together at a livestock exchange and go to college together. He's 22 and I'm 18 if that matters. We hangout pretty often outside of work and just had sex for the first time together the other day. I tell him I have feelings for him and I like him and he says he does too and or that "I'm like the best" or "Very nice, sweet, and cute". He says I'm beautiful and kind and what not but I know he says he has a hard time with relationships and he didn't expand on that. Plus with work and the fact he plans on moving, he doesn't want a relationship holding him back. So I get that.

When we first started talking he said he liked this one gal, and before we ever did anything I was telling him maybe he could get her some flowers or go on a date and stuff. Like 2 weeks ago he says he actually hasn't seen her in over a year and he doesn't know if he would actually do that.

So we have this thing going on and I enjoy it and I'm happy and he's truly great and he said if things ever change he'll let me know and like he isn't opposed to a relationship in the future (It's because if he moved for work he doesn't want it hold anyone back.. as I explained earlier) so I appreciate that but I guess I don't know if I should let myself get attached or keep it as simply casual? Cause I do already really like him.
