Well, this sucks, been there.

The answer is to play it cool. Assume you're the catch.

You and I both know these "friends" only want to fuck the girls. It's that simple. They are beta's, male orbiters, whatever.

But over the years I have found that freedom and slight indifference will make you stand out to your girlfriend. If you act like you're fearful of this dude banging your girl, it will have an attraction lowering effect. You're the catch. You have no worries...if she cheats, you'll find better, etc.

However, in your situation I wouldn't appreciate the one on one time. I'm cool with group outings.

I do not act possessive or needy. I simply tell whoever happens to be my gf at the time that I was asked out for a drink from a girl who is "just friends". And I'll up the ante and make it a 9 pm type of thing. This will usually get the girl to freak out, and I'll simply say "hey, I was cool with you and John at the burger place. " This of course will conclude in a talk about boundaries, with her bringing it up. And thus no more one on one time with John.

Girls are emotional beings, and often times logic and explanations are lost on them with matters of the heart.

Unless she's given you a reason to ever doubt her, you've gotta trust her man.

This looks like your issue, not the relationships don't make it that.

I do think its fine to bring up with her without pointing fingers so that means staying with you and how you feel, not bringing her into it but that you feel a bit anxious about it.

Yea I see what you mean there too, so how would YOU go about talking to her about it? and also,

What do you think of the other guy's little plan? I feel like it's best of both worlds, get to be unreactive-ish and also eventually talk to her about it.

I am bugged by this situation:

GF basically tells me she is going to go eat at this sit-down burger place right next to her work with a guy coworker of hers that I have never met before after she gets off work (she is a waitress). I trust that she won't cheat (I do have a mild fear of it, however) and I'm fairly certain that the coworker is aware that she has a BF cuz from what I've seen/heard my GF always tells dudes she has a BF. It is still bugging me though because the guy is probably trying to **** her and sees this eating after work as a "date" opportunity....So I am bugged by the whole thing especially because I have no idea how I'm supposed to react.

When I was on the phone with her I was very unreactive and was actually surprised she would even be open about telling me that, but then the annoyance dawned on me like 5 minutes after hanging up.

On one hand, if I say something she may think it is possessive, and she'll make a naive comment about how he's "just a friend", but we know guys rarely go eat with a girl they aren't trying to ****...there's almost always an angle.

On the other hand, it's bugging me because I wouldn't hangout with a new girl I just met 1on1 out of respect for my GF and our dope ass relationship...it would seem disrespectful and unethical.

What the hell do I even do or how do I react? I know she's not cheating or anything, but it just seriously annoys the **** out of me.

We have an amazing and loving relationship, we have some arguments but resolve them very well and mature, nothing like this has come up since we started dating.

If a female coworker asked me to get drinks I'd say yes, but it doesn't feel like the same thing to me.

I guess you are correct about the one tactic being passive aggressive, it's clever but i don't want to breed insecurity in the relationship.

She ended up texting me a few hours later and saying "Hey I'm not going anywhere with my coworker anymore, do you still want to hangout?".

So I ended up seeing her right after she got off, she met up with me and we fucked.

I won't bring it up for now, unless it becomes an actual problem. I should have set my boundaries earlier on, I never mentioned anything about that sort of shit so I can see why she would assume it's no big deal.
