I don't think you can. Have you seen what a whipped man looks like? That is a man who is fully engulfed in anti-manlaw behavior. All you can do is sit back, laugh, and hope he doesn't build a wooden horse full of random soldiers intended on destroying a city-state.
Then again, you could always just kidnap him and take him to a secluded warehouse, tie him down, and force him to watch re-runs of The Flintsones. I figure that would make anybody come to their senses, if not be willing to commit some sort of crime which is definitely unwhipped behavior.
Here's the other thing though, its kind of fun to see a guy really smitten behind a woman. Most of us guys spend so much time trying to pretend that we're too cool for love and romance so when you see a guy whose clearly in love and losing his cool behind a chick, its fun for a little while. Well at least until that dude becomes unbearably ridiculous about his love and unwilling to hang with his friends anymore or go anywhere unless his girl is involved.
I think that dude just needs a reality check, or an intervention. You have to have a real talk and let him know what he's doing to his friendships and himself - basically becoming a Douchey Mcdoucherstein. And no self respecting man wants to be THAT guy.
The thing is, I asked this question-I'm a lady. He knows she has his balls in a rheumatoid arthritis grip, because he has to sneak out of the house to see me. I HATE to see him as unhappy as he appears and he keeps telling me that he has to get out, but I don't see any progress. So do I just be a friend, watch and wait?
Honestly the only thing you can do is wait and be a good friend to him and be supportive. No good will come from you pushing him, he has to want t get out of the relationship and do it himself.
I am in the same exact situation! My best guy friend lies and sneaks around nearly every weekend to hang out with me and our other friends. He has also confessed that his gf HATES us...I have tried befriending her because I am afraid we will eventually lose him but that has just not worked out. He also says he wants out of that relationship, which he's been in for 5 years but can't seem to end it. I've already expressed how miserable he seems to be when he's with her but I guess I can now only be a friend, watch and hope he'll come to his senses.
Well, I don't see why you feel like you have to get involved. I mean, clearly, he can easily solve his problem. He's just choosing not to as his girlfriend is more important to him than your friendship.
