When i was still dating, I've now been married for over 5 yrs, it was either you're with me and want to be with me, or you don't. There was zero tolerance for guy "friends" as i didn't believe in them. When they are single, thats fine, have as many suckers sweating you as they want. but if you're in a relationship with me, see ya later to the "friends". Friends of the opposite sex IMO and based on all reasonable facts, are all based on attraction in some form or another. If she can't handle this stance from you, then you know she's not for you. Plain and simple. She's either into you enough to drop these other guys, or she's not. From my experience this caused conflict at first, but usually had the girls hooked after some time.
