<human>: I've (27/f) been talking to this guy/28 (text, email, fb message) for several weeks - we work together and have sort of known each other for a couple of years, but never much more than saying hello or a little harmless flirting over the copy machine at work and we finally started actually talking to/getting to know one another. Last night was our first sort of "date" (he came over to play my old school Atari and watch a movie) and midway through, he gets a call that his mom has died (she had been sick). 

We've been doing some serious sexting leading up to this and were both really into hooking up last night, and he actually stayed and we had sex several times anyway (I'm not sure if that was a particularly good idea, thinking back). Today, I hear nothing from him - I sent him a quick text this morning just saying to let me know if I could do anything and, obviously, backed off after that as I figured the last thing he wants right now is some chick blowing up his phone if he doesn't want to talk. Is this the right response? I'm just not sure what to do here...we're close in a lot of weird ways, but we're obviously not at a super emotionally intimate level in our relationship. Am I right in backing off and letting him come to me??

Could you distill the essence of the text into 1-3 sentences?
<bot>: new guy I'm dating gets phone call mid-date that his mom has died - finished date/had sex, now haven't heard from him and don't want to handle this situation incorrectly.
