I don't really have anything to say about the whole issue/rantfest in the OP, except to say that she doesn't sound like the brightest bulb for marrying this guy at 19, but yeah, people do make mistakes. I hope she gets her shit together.
What I am here to post about are all these posts about how it's "wrong" for a married woman to have male friends and hang out with them. I'm sorry, but that's absolutely ridiculous. As a married woman myself, if my husband had ever... no, I won't even go there. It's just stupid, and he isn't stupid, so he would have never (and has never) exhibited any paranoia or jealousy about me hanging out with my male friends--who make up about 80% of my social circle. C'mon, guys. If someone is going to cheat or screw around, they're gonna do it whether or not they're "allowed" to hang out with members of the opposite sex, so acting like a goon and laying all these ground rules tends to just make things worse.
But I've seen it so often from people, this kind of behavior, like when a woman gets married, she should no longer talk to anyone other than her husband or other women. That sounds stupid, doesn't it? And yet if you examine these attitudes, that's what it comes down to. It reminds me... I had a good friend for a while (we eventually fell out of touch) and his father would actually yell at him for hanging out with a married woman, like OMG HE MIGHT GET SOME SIN ON HIM or some shit. There was absolutely never anything between us--most of my guy friends are like a series of brothers, and that's how it was with him, too. But if my name came up at all, holy shit, it was like he'd just kicked someone's puppy.
I just do not understand it at all. I cannot imagine life without the freedom to go out to dinner with classmates (mostly dudes) after night classes or go over to my best friend's house (a dude AND and ex-boyfriend) to play Rock Band.
I guess my husband is just secure. He has no reason to be otherwise, and he knows it.
eta: In this situation? Sure, the girl is clearly conflicted. But that's because she's 19, y'all, seriously, and probably shouldn't have gotten married in the first place. That would be the same whether or not she was hanging out with dudes.
