How serious is he with her?

I'm friends with this guy. He has a girlfriend. They have been going out for a month but they were best friends before they started dating.
2 nights before he asked her out, he had sex with another girl. He makes sex comments to other girls to their faces and he let me and another girl sleep with him in his bed (me and the girl slept with him on 2 different nights).

But 2 weeks ago, when his girlfriend tried breaking up with him, he got really upset and begged her to stay with him.

So why is he making sex comments to other girls and letting other girls sleep with him, but getting so upset when his girlfriend tries breaking up with him?

 

It's Called "Playing The Field", And All Of The Girls In

His Life Are Being "Played" For Fools....



Cheers Glen.

 

It's a matter of pride for some men. It probably results from a bit of insecurity. No man likes being broken up with, but usually are fast to break up with a girl or fuck around.

 

Hard to tell it could be a couple of situations some of which have already been mentioned. By the way, what's the general age of all those involved OP?
I get the feeling you all are pretty young and still experimenting.

1.What Glen said; he's just playing the field.

2. He really does like her but he's not ready to settle down and so he keeps playing.

Either way he's got a problem in my opinion if he's willing to put his girlfriend through this ordeal. If he wants an open relationship he needs to face facts that it may not happen with his current girlfriend.

 

Sounds like he likes to have have his bread buttered on bothside .

 

so he had sex with someone while he was single, he was vaguely flirtatious (but never acted on it) with some other girls at an undisclosed time that i seem to remember you saying previously was also when he was single, and he let his friends use his bed without ever trying anything sexual with them? what does any of this have to do with his girlfriend?

 

^ This is true IF you interpret the OP's post literally.

I believe the rest of us, inferred that the phrase "slept with him" meant sexual activity took place between the guy and various girls including the OP.

Meh, we'll see if the OP responds or not.
