Sorry to be dense but what are you ending exactly? I am going to gather (and pardon me for being so blunt) that the two of you had sex. You said you didn't really know this person very well prior to this happening, correct? So what is there to end really? You aren't dating, you aren't in a R... IMO the question you are asking is "should we START something?".
What sort of feelings are the two of you having? Not knowing somebody well then having sex is an awful big leap! Do you *want* to get to know this person better or is it all stemming from the one night?
I am really so very, very glad to hear you mom is doing well! What terrific news!
