I would agree that "tagging along" is placing the frame in her hand (essentially saying: okay, you are in control I submit to your agenda and will place myself amidst the running to spend time with you").
I myself, would have immense trouble allowing a girl I'm with to have 1:1 day with her "male buddies"...some might say this is "insecure" or even some might say "possessive" but I have to ask, is it really? I'm not forcefully making anyone do anything -- more than anything, I'm saying, it makes me incredible uncomfortable because I'm not naive to the nature of men and "friendships" -- I woulds say even in Iqqi's situation that of course her BF and that chick have some undertones there -- whether they've acted on it or not -- or take the guise of friendship, doesn't mean that there's still not some emotions within that. I just don't see how any self-respecting man with a penis wants to be friends with a bunch of girls -- 9/10 one person is madly in love with the other, and that other person is the blockage to any intimacy or relationship -- yet often the other is kept around either to not hurt their feelings *because of the great friendship*...
From my life:
1. I had one good female friend who I definitely was in love with. This was during my major AFC days (I'm maybe a mild-light AFC right now..stil in the works gents) but goddamn she would fvck with my head. More or less, I could have been sexual with her, pursued her from the stance of "lets take it slow" and got completely friendzoned -- yet there was always some tension there and she even revealed how she'd have "more than just friends feelings" for me --- but then bounce back into friendship...it was all a mind game and after years with this girl as my friend I came to the conclusion: fvck this. I'm done with female buddies. I'm not saying I'm an @ss -- I'll be friends with my friend's/relative's girlfriends, I'll be nice to her friends, I'll be myself and enjoy their company -- but the only 1:1 texts/hang-outs/correspondence I make with females these days is strictly in regards to those that are helping me get better what I want...otherwise we are stuck endlessly in losing situations. Some might call me a 'bad guy' because I specifically removed a female friend from my life because of her inability to ever want more than friendship, but why? I was tired of getting mindfvcked by lovey dovey post cards and gifts from her with nothing on the other end -- the second I tried to get closer she'd run.
2. My recent last LTR in the very beginning was "hanging out" with an ex-bf and a complete AFC dude who had a major crush on her. They would get together and make music at her house. This girl is an AW for certain -- I told her it made me incredibly uncomfortable. I told her this dude was schmoozing all over her and how couldn't she really "see" her ex-bf was looking to get some side-action and this AFCchump was looking for his chance....after this discussion 2 things happened:
(a) she stopped hanging out with both of them in any 1:1 situation.
(b) she then tried to use this as leverage against me later saying "I don't feel free"...that my feelings of "jealousy and insecurity" made HER feel that way too (I was working in an outdoor job where I had to live on-site with a male and female roommmate) -- and my living with a woman to her, was a complete double standard..
But the difference was not only did I not enjoy living with that woman myself (she was incredibly annoying), but was forced to via work, and third never spent any 1:1 time with her...
She on the other hand, was actively seeking and entertaining these AFC dudes.
When a woman is actively seeking and encouraging outside male attention during a relationship = bad bad bad mojo. And they will try and make you seem like a possessive douche, but seriously come on -- if the other side of the coin was flipped MOST women would be incredibly insecure. And they OUGHT to.
Working with other dudes, being around other guys because of friend's boyfriends, etc -- that's one thing. But all of my experience is telling me that if some girl has lots of guy friends she is just schmoozing in the attention -- whether they want to admit to themselves what is really going on or not is another story -- half of these females brainwash themselves and convince themselves that they've got all these really great guy friends and sure, nothing about their vagina or the shimmer in their hair or their sexuality has anything to do with it, "just friends" she says.
You know how my situation ended for me? Bad. What I should have done is (1) notice she's got lots of guy friends, and say (2) say, "I'm sorry, I'm looking for a girl whose willing to be responsible entering into a relationship...you hanging out with other dudes who are trying to court you ain't going to jive"...but alas I was hooked on the pootang.
OP -- this ain't cool man.
If she "totally gets it" why you feel that way, why the fvck doesn't she respect your position/feelings and cut off ties from her ex?
She is going to self-sabotage any relationship with a good man by hanging onto this dude emotionally. She doesn't get it.
And that's not fair to YOU. Are you being emotionally available for her? IE --not carrying past suitors or relationships? If you are emotionally free for HER, she ought to be on the same page. Otherwise you are short changing yourself. As good looking and fun as she is (lots of girls can be both of these yet still entirely psych0 and not good relationship material) she is hanging on man. YOU deserve better than that -- and if you caught her given her attractiveness, there is no doubt there is an equally attractive woman out there who will be more mentally available for you.
