Depends on the woman, the level of connection, level of interest.
There's a former crush (tiny bit of a crush still there); story of my life. Not interested. Wouldn't even give it a chance. She has had several boyfriends.
Honestly, they seem like really good guys, so, well, if she isn't interested in me, I'm at least glad that she seems to have the sense to pick some good guys. I feel a twinge of frustration and maybe a tiny bit of envy, but honestly, I don't hate these guys, and we're on friendly terms. It's not personal with me.
I'm no competition to anyone, so there's no real need for that very often. I try not to hold grudges against people that don't deserve it.
There are guys who really p*ss me off. But not often.
Similar to the "jealousy" aspect, sometimes we men get a little "brotherly" if we aren't intersted in the girl but we love her as a friend. I feel protective of my real friends.
I have a good buddy, now he can kick some butt. He's a huge guy. And just so you know, I'm a little guy. I'm 5'7; 150 pounds. He's like 6'3 and works out constantly.
Well there was this time where my friend wasn't around, and this old guy (we both knew) started talking to me. Then the old guy started talking about my buddy's sisters in a dirty way, and suddenly I wanted to punch this guys teeth out.
It felt really strange, since I'm not really all that close with his sisters, and his sister's are attractive, so I bet they get that a lot, but I felt this urge to smash his face in. They're awesome women, so I feel a little over protective sometimes. It was as if he was talking that way about my sister.
All I did was warn him that if I ever hear him talking about my friend's sisters in that way again, I was going to punch him.
It was actually quite funny I suppose, (especially when he kind of backed down) but I was ready to fight this guy. I was seething p*ssed off.
I have a woman friend that I've been friends with for years. I'm not interested. She's not either. So, a few years later, she announces that she's engaged. While happy for her, I suppose maybe for a tiny while I had a jealousy about kind of "losing her" as a friend. I didn't really know him well, so I suppose there was a hint of awkwardness, like one of those non verbal "if you hurt her" warnings, though I didn't really think he would.
I suppose that on the other side of the coin, for a short while, her fiancee felt a little bit of competition over her with me. It certainly felt that way. I think that by now he's gotten to know me enough to know that she's not someone I'm interested in and that she's made it clear to him that she loves HIM.
Now we're really cool. It's almost like I gained a friend in law, and got a better relationship with my "sister" when part of me kind of thought I'd lose her friendship after the wedding, and it seems like all that tension was gone since we've gotten to know each other better.
