<human>: Can you succinctly summarize the text in 1-3 sentences?

I think it would be wrong, and unfair, for me to ask my GF to NOT have male friends.  So at this point, I no longer venture down that path. 

I know that she will be physically close and touching each other, as they share a passion for work-out, acrobatics, lifts, and circus-like stuff. 

While it goes without saying that physical intimacy is off limits, it does irk me as man, to think someone else is able to touch her. 

I can't seem to put down the threat in my head, that their might come something romantic between them.

Just the thought of them getting together to workout seems to fuel jealousy in me, along with all of jealousy's uncomfortable, unpleasant and irrational thoughts… 

My GF had very controlling parents growing up, so now she really doesn't like boundaries set, so based on our talks, it is sort of 'her way or the highway'.

I guess I'm left to find a way to be comfortable with this situation, and not see it as a threat. It honestly bothers me often, weather I like it, or not.
<bot>: GF doesn't like to set limits on what behavior is OK or not OK, between her, and her male friends. The result is that jealous me can't find the predictability or safety I want in a relationship.
