Hey there LegendBoy. I know where you're coming from- I used to have bouts of insecurity as well.
But honestly, the best method is not to "fix" your GF (ie. make her stop talking to random guys on myspace), but to fix yourself.
Step back from your jealousy for a moment and see where you're coming from- do you have any how much of an insecure, female dog you're being?!?! She's chatting with people on myspace, great! Before you know it, she'll be giving guys blow jobs in your toilet.
I know at first, it feels like that, but we really have to step back from our mental "apocalypse" projections, and be a little more rational. Chances are, you'll never meet a girl without a male friend or two. Heres the way I see it:
If you wanna have a hot girlfriend (and you do, right?), then you gotta accept the fact that guys will be hitting on her. If you're too much of a wuss to handle that, then find yourself a fat, ugly hag for a GF (and even then, there are some pretty DESPERATE men out there!)
Blusher said: "That's a major Red Flag. Dump her.
My LTR doesn't have male friends, no MySpace and doesn't go to clubs.
Just the way it should be. what would you have to deal with all that bullsh*t?"
I believe that's just insecurity on your part Blusher. You know the ancient Chinese tradition of bound feet? They bound the feet of married women so they couldn't run away from home and cheat. Male insecurity at its greatest. Obviously, I've never met you so I don't know, but thats just what I see coming from your post.
