She should get her hormones checked or ugh! read 50 Shades of Gray. But I suggest the hormones first.

She's got you locked up and doesn't have to try anymore. Your needs are unnecessary. If you don't want to accept that then pay up. I assume you had a decent sex life at one point? If not, then you are a chump to have married this broad. Get your cheque book out...

Perhaps you truly are the caring, compassionate man you say you are, I don't know you personally so I can't assume one way or another - but - your wife is missing something in her life that allows her to feel the need for intimacy. Could be her issue alone, could be that you think you are doing all the right things but aren't really. Have you sat down and really listened to what she needs / wants? Has she ever really sat down and thought about what she wants / needs?
If you can afford it go to a counselor and see if you can both improve on your communication skills -- you might just find the tools you need to reclaim (or ignite ) the intimacy you both need.
I wish you both luck - being lonely in a marriage is difficult.

So sorry , if it were me (and it was) I'd leave , but only after I felt I've done everything I could to try to change it . I had an almost sexless marriage for 11 years and tried everything . Some people just aren't sexually compatible end of story . Don't waste more time just go . And on a side note : my ex husband now says it was all linked to his self-esteem , and that he wishes he had given his head a shake ( not that I'd ever take him back ) good luck whatever you do

You haven't found a way to feed her libido. Go to work; are you really that stupid and boring? Maybe she and you deserve each other.

insist on couple's counseling. get a good counsellor. good luck.

I didn't realize it was affecting your marriage. Ok then; I'll tell her that it's over between us and maybe things will work out for you. Sorry dude.

@I'm a chick - I think your ex's comments might apply here. The problems could really be from her poor self esteem. It fits a lot of other things. Of course in my poor self esteem moments I could think that PF and Joules are correct!

@Anon - I've read 50 Shades (pretty crap piece of erotic fiction - Ive read much better) but she would never-ever-ever read it. It apparently did do wonders for this other couple I know!

Have mentioned counselors but not well received for reasons that I do understand. I have spoken to a couple of professionals in this field myself for advice (sadly it usually works better if both get the advice).

Thanks all and I think A sums up my feelings nicely with " being lonely in a marriage is difficult"

But she hasn't had her hormones checked. There could be an underlying issue. Stress, diet, lifestyle can all affect the libido. If you can rule out physical, then it's the relationship that has lost it's spark. It happens with routine and trying to make a living.

If there is any love still between you two, then maybe you can still rekindle the spark but of course it takes both of you to want it.

Perhaps some time apart to think about what you both want is warranted.
