I wouldn't normally go to such extreme effort as to quote TWO posts, but here we are.

Ok so we can all agree you have one thing that's bothering you.

What's key is what's highlighted in bold, yet that still comes back to that one thing that bothers you, the mundane sex.

All I can say is, I've been in those exact shoes earlier this year. And long story short I regretted the decision to finish with my girl over unfulfilling sex. There were other things I could have done such as simply talking to her about it rather than abruptly ending it then hurting a few months later. But I think you've already talked to your girl so that's a slight difference than my situation.

Actually, that just makes me now realise kowalski might be right in his original post that there's no way back.

Perhaps that's harsh and not wholly accurate, in that there's still a very small chance, but a small chance it is.
