Hmmm. So coming to GAF for some clarity.
Me and the girlfriend have been together nearly 5 months, so we're getting pretty serious - things are great, wonderful even - but I'm worried there might be an issue coming out of my camp and I want to nip it in the bud.
So I have tons of female friends, tons - like 2/3rds of my many friends are female - and while the girlfriend was a bit nervous about this the first few weeks we dated, she quickly realised I have an extremely well worn healthy relationship with most of them, and that nervousness seemed to vanish. Unfortunately, it's not done at that - as there is one particular friend that makes her mildly nervous. She's someone I met last summer, and in all honesty - when I met her I was in the phase of my post break up (first girlfriend post breakup) where I was looking at all single girls as prospects, so obviously I looked at her as one. Nothing ended up happening, I met other girls, and eventually my girlfriend and me and this girl just became friends since. Well, me and the lady are very open and honest and we tend to lay out everything when it's requested so she knows all that, and that makes her a touch more uncomfortable with this girl than any of my other female friends, but she was very upfront an honest and said "I don't want to be the kind of girlfriend who gives you grief for having female friends, I trust you entirely and even if this girl were to make a move, I know you wouldn't reciprocate, and I would just go and kick her ass after" - she also wants to make an effort for be friendly with this girl, so a little while ago she even suggested they hang out - and I think they have something planned in a few weeks.
Anyway, the last few times I hung out with this girl, I've noticed she's been kinda different around me, nothing substantial, but I just couldn't put my finger on it, until she started getting drunk. At one point during a party she comes up to me and says "You and your girlfriend are so cute it's making me gag, and... if I am honest, a little bit jealous". That was red flag number one, and since then I've noticed a few others. I'm not going to go into detail, but I am pretty sure that this girl has either just developed a crush on me or was hiding it till last night. Last night we arranged to hang out, as we hadn't seen each other in a while - and she also was gonna help me out with some skin care stuff to thank me for working on a website for her, and also make me dinner. At this point I wasn't really sure if she had a crush on me or anything, or if I was just over thinking it, so dinner and hanging out sounded fine.
Well we went out first, had some drinks and blah blah blah, talked about some stuff and slowly throughout our conversations I started to realize - no, you weren't crazy, this girl totally has a thing for you. It culminated when we got back to her place and she started to ply me with shots (I will never drink tequila again in my life, I barfed so much) - she didn't make a move, she didn't suggest anything... but looking back with sober thoughts I realize that she was literally just trying to get me drunk off my ass. Eventually I felt a bit uncomfortable and left, got home safe - and all was well. I talked to my girlfriend sporadically throughout this whole thing, and apparently sent her many affectionate drunk texts and one midnight drunk phone call - and that made her feel much better about the whole night and this girl, and she doesn't seem nervous anymore.
So, now that the long ass and probably unnecessary story is over, I go to the crux of the post - what should I do? I mean, first of all... this girl has a crush on me at least... but she never made a real move or anything, so I don't feel upset at her - for all I know nothing would have happened had I stayed at her place longer, so I don't want to make any brass accusations. But do I give my girlfriend all the details and my conclusions? Should I continue to encourage a friendship between the two? At the very least, should I not hang out with this girl alone anymore? What's GAF's opinion? I don't want to start drama, so... I kinda just want to swallow my worries and hope for the best right now.
tldr; found out a friend of mine has a crush on me after a night of drinking with her, nothing happened, should I tell the girlfriend my conclusion or just keep that shit to myself and avoid alone time with friend?
