need advice

so i’ve been seeing this guy for almost 3 weeks - we’ve been on 5 dates now ranging from going out to just hanging out in his apartment. i last saw him on monday (today is thursday) and on monday we got dinner and we were talking about our families and stuff and he mentioned that he wasn’t sure he could handle the responsibility of being a father and i mentioned that i want 3 kids. after that we went back to his place and watched a movie and then we ended up hooking up. we were kissing and he was giving me some hickies on my boobs and sucking my nipples and he eventually ended up fingering me and i came. after that i started to give him a handjob, but it was pretty dry. after a while he stopped me and said i didn’t have to. he explained that he’s on a medication that makes it harder for him to have an orgasm and that it usually takes quite a while. he said that it was also just pretty dry, that it wasn’t anything i was doing wrong and that that was just the nature of handjobs, even during masturbation it can get pretty dry. so after a while we stopped and just ended up laying there and cuddling and i told him that he was the only person who’s ever been able to make me cum, and that i’ve only been with one other person but he was never able to. he kind of laughed and said thanks for the confidence boost, and he invited me to spend the night and i said not yet, but hopefully someday. (i know he didn’t mean it just to have sex, because he said that he didn’t want to go any further on that night than we went). it got late so he walked me to my car and kissed me goodbye and bit my bottom lip, which he does a lot. but now i haven’t really talked to him much since then, on tuesday i got one snapchat from him, two on wednesday, none today. i’m worried that i freaked him out or that he doesn’t like me anymore because he didn’t cum that night? but it’s also midterms week at our college so it’s possible he’s just busy. i have trust issues after the last guy i was with, so it’s hard for me to gauge whether or not i’m overreacting. help!!
