IM frequently less than HO where you go from here depends on the GF's take on all of this.

My spousal unit has some post-traumatic issues in this area and fairly low libido. She's well aware there's an issue here and we are working together to resolve the issue; things are getting better and the reason they're getting better is because we're both actively working to resolve things.

One reason she might not enjoy kissing is that kissing can lead to sex and she feels pressured. Better to not start something you can't finish ;)

I have ended a relationship because my partner refused to address this particular issue, so for me the decision whether to stay in the relationship depends pretty completely on whether my partner is willing to work together to resolve things.

There's some emotional trauma, a chemical imbalance or both going on here. If she's willing to do what it takes - and what it takes almost always psychotherapy for both of you and may involve medication then the work is worth doing and she's most likely worth keeping :)

But - if either she or you are unwilling to do what it takes you might as well stick a fork in it now.

One thing, though - you need to understand the cycle of guilt that goes with this kind of issue. She most likely knows damn well that she's not holding up her end (literally and figuratively) and harping on the issue just makes it worse. If you think you feel unwanted and unattractive, take a minute to think about how it feels to not be able to be intimate with someone you love.

She has issues to work through, you both have some issues to work through and you need to completely take the pressure off so she can heal in a safe environment. It will probably mean that you're not gonna have sex real often anytime soon, but if she's willing to do the work and you're willing to be satisfied with progress then things can work for you.

But - don't whine, beg, pout or complain; this just makes things worse. You guys need some help - so if you're both committed to the relationship, do the work and get things fixed. If one or both of you isn't willing to do what it takes then there's probably cause to reevaluate the relationship.

Good luck!
