***edited: did Brenna's answer get pulled, or did she delete?
I think Brenna's answer is really sad. Perhaps the guys SHE knew are like that, but there are some great, quality men out there who actually know how to think, and there are some great, classy, quality women out there who can be friends and not flaunt themselves and make everything about sex. Please. YES there are guys who are dweebs and want to have a relationship of some sort that isn't exactly what the woman has in mind (be it physical, or dating, or whatever), but YES men and women can be friends.
One of my very good friends from high school....we were....substitute or interim bf/gf, in that we were best friends and went to the dances together, there were a few make out instances but that was our age. He was an exchange student, I'd just broken up with a long time bf, neither of us wanted to be alone our senior year and we TRUSTED each other. We've been friends all these years later (16 years) but we just chat on the phone a couple times a year (birthdays) and send out public comments on each others' walls (facebook). We're good buddies and I'll chat to him online while he's preparing to go on TV, and watch him live via internet (he's a news guy in Moscow now). We're really friends only, and would never be anything else, even if I was not married. Our lives are opposite, but interesting to each other (but not enough for either of us to change!!!) My husband did mention that he's a little jealous of him, and I was seriously dumbfounded by that. Jeremy says the guy is very good looking, has the whole Spanish accent going on, is a public figure on TV, very worldly and speaks a few languages, owns 2 winning racehorses, etc BUT that's seriously not the guy I see at all. I think he'd be a catch for someone if he ever wanted to settle down, but he's not "that guy" to me and wasn't a decade ago either! (I had to remind my guy he's hot, has the English accent going, is worldly, is learning Spanish with the family, has 2 beautiful kids with me, is a FAMILY MAN, and my true love). But out of respect for my husband, I don't chat live to my friend unless husband is up and about with me, and neither of us are much for writing more than a quick comment on the FB wall anyway.
I have another very very dear friend (since 1989) who is my basically my brother. He even LOOKS like my brother! We used to hug and hang on each other a lot, but that might have been intoxication more than anything. Even though we think each other is cute, we'd never in a million years consider anything. That'd be incest, lol. My mom really wanted me to date him when we were in school and I had to gently explain that he is the best friend a girl could ever have, but the worst boyfriend a girl could ever have. A heart of gold, but I haven't got a clue why girls were stupid enough to date him. My husband is not concerned with that one at all, I think he actually considers him a bil also. We both went through very hard times as kids together, things noone should ever have to deal with, and we did it together. That, and a few incidents as teens...gosh we're blessed to still be alive and kicking! I think that forged a bond, and sheer loyalty that can't be broken and goes way way deeper than stupid sex. A true friend! He also took very good care of my grandma (who lived 10 hours away, but 1 mile away from HIS grandma who he stayed with after school). Now that we're both married, we do the one armed hug and double pat that you do in sports, we don't squeeze tight and bear hug like we used to, out of respect for spouses. He does still hug my mom like that though, lol. (Who by the way thinks my husband is God's gift to me, her, and the world).
I've seen that my relationships with guys have changed since marriage. But Jeremy takes the place that the other guys used to fill, as it should be. I don't seek out guy friends. We DO try to go for married couples. Sometimes you may like one or the other better, but you take the couple as a couple. I do not go out alone with my guy friends, we have group stuff. One of my friends is from "back in the day" and we all went to school together, and he's the only single person left. He joins us, but if I'm spending time with my guy friends, it's a bbq, sporting event, or tubing down the river all of us (my husband, their wife or gf, all the kids, etc). It's just easier on all involved to avoid all appearance of evil, as the Bible verse says. Same thing of my husband and my brother, both men I have the UTMOST respect for. They have female friends, but keep it family oriented and with everyone around. I don't think they're very close to the girls (my brother isn't really "close" with anyone but me, his wife, and one guy friend.....my husband is the same......he's close with me, my brother, and 2 guys.....but they both have casual female friends and are also friends with the husbands....all groups have been to the house for crawfish boils, UFC fightnights, potlucks, and game nights).
ALLLLLLL that said, if a guy said your husband should say no, then he is saying he's attracted to you and thinks something could happen if in the wrong situation. Respect the fact that he's honest with you and don't mention it again......but also don't do anything one on one with him. He's let you know.
