So ive been seeing this girl on and off for about 2 years... No commitment just sex...id be lying to myself if I said I didn't care about her though...we connect on a deep level and have shared deep secrets with eachother blah blah blah.. anyways she started pushing for a relationship about a month ago but I told her we're better of continuing as we are..long story short I'm sure she does her thing on the side just as I do mine...I'm not a jealous guy, I never ask about who she sees or where she goes but what got me upset is a few days ago my best friend sent me a screen shot of her asking him to come over at booty call hours, I played it cool and told him go ahead and go but he didn't...It may sound dumb but I can't help but feel disrespected. Idc if she fucks other guys but to go for my best friend who I introduced her to and after just telling me she wants a relationship and all that other shit. I know there's no commitment but dam I assumed friends and family were limits! My first instinct was to call her and curse her out, second instinct was to show up at her place with my best friend and confront her but after thinking about it for a minute I think it may be best just to go ghost with no explanation, what y'all think?
