i hate how this always gets turned around back to something the dude has done wrong.
she simply doesn't have a sex drive...so as far as her needs not being met, he rarely has a chance to meat them, sexually speaking.
now i guess it could be other needs, and that's how it usually is...but he makes double what she does, is a stable and sober guy, will be a great dad, etc...so imo he is more than meeting the needs of her.
