Been banging this chick and sleeping at her place for nearly 3 months now. She's always been quite submissive, is happy to initiate blowjobs, down to meet whenever I want, gives me 0 drama, is ok with keeping texting for logistics, hasn't brought up the talk, gives me weed and breakfast, likes to get lovey dovey and do cutesy shit I enjoy as well, opens up to me and even tells me nasty shit about her bestie (which I'm supposed to keep secret) just to keep me amused. She knows I'm leaving town in less than 2 months. However, she got introduced by her bestie to some dorky orbiter of hers (by hers I mean her besties), was asked by her what did she thought of him the morning after (my girl replied he was 'nice'), they started following each other on ig, spent yesterday evening with a group of 5 people including dork and bestie and was online at suspicious hours (12am, then again 7 am, then offline until 1pm. She's more or less a NEET so I don't think she wakes up early). I know I'm giving too much thought to this and I'm more jealous than I should be over a FWB, but I don't want to hard next her cuz the pussy is good, this is really a small town and I don't have that much time left. At this point I have the right amount of feelings to naturaly do amused mastery and enjoy how cute she is when she acts like a happy little girl around me while not actually feeling like seeing her more than 1/2 days a week. As a narcissist, this might be difficult to keep up (and thus I'd have to disregard the cutesy shit and focus on her ass and tits) if I found out she's fucking some other guy or if I had a persistent suspicion that she's fucking some other guy. Whadda ya think? What do?
