Yes, she just met him for a month during a language course. So they just cant become 'friends' in that short period of time. Besides, she does not have guy friends, any other guy friends I mean, just guy she knows from college, or work etc.
I think the right option is to set some firm rules from the begining. I do not like her to hang out with other guys, thats final, thats it.
Anyway, I previously said that one thing is being too permissive and the other is being to controlling, in the middle point is the right thing to do.
Because as I said, lets say you're super alpha, cool. But you just let your girl do whatever she wants, go wherever, whenever, with whoever. She meets one guy here, one guy there.. one player, one afc, another player, another guy...over some time. All this because you're so confident that you just allow anything.
You may get to a point where your relationship has some problems, and since she's just going out witch whoever, whenever, getting hit on over and over, meeting new guys everywhere... she may end up cheating on you.
You get my point? if you let her be exposed so much, you cant blaim her if under certain circumstances (relationship problems) at some point she finally cheats on you. Since you seemed you did not care what she did...she went out over and over with her single female friends...got hit on, you kept saying it is fine to go to party, hang out with guys etc, here is the result. Yes, your super alpha, so? there are other alphas out there thay may have better game.
dont you think?
If you had just set some rules, you had shown you care what she did and with whom, you had shown some healthy jelausy, she would not have end up cheating.
Dont you think? so being that permissive is a mistake.
P.S.
I would find it very weird, if she did not care I hanged out with female friends, or talked too much with some girl, etc etc I would think she just doesnt love me. Dont you think?
