I'm with generic on that one. Fuck the others that say dump her. That's the problem with people these days, first sign of trouble they tuck tail and run like a bitch. I have been married for 2 and a half years, and sometimes it sucks ass, other times it is great and the best decision I ever made. Sometimes longevity is worth it's weight in gold.
On another note, I too suffer from "chick with no libido" as her depression meds suck that shit right out of her. What can I do? She knows that I have a libido like a fucking 90mph train, so she hooks me up when we have time. All you have to do is avoid being a prick about it. When we fight about it, we go to bed mad and I still don't get any. When I am cool and all cuddly and shit, It isn't fun but I get laid... It's an investment... Good luck, don't give up. Personally, I am waiting for my wife's sexual peak, as she is 25 and I am 26. I feel like a kid waiting to turn 21... Good luck bro...
