Sexual needs are very important - you're entitled to yours and she's entitled to hers. And that's that.

The problem is that while she may not need much intimacy, you clearly do. Do you feel this is something that could lead to you falling out of love with your wife? I'm not referring to how you might act upon that but whether you think this will bode well for your future situation together regardless of whatever compromise you come too?

What constitutes a marriage is a very personal thing - but one thing for sure is that is usually entails some long held commitment. If you don't think you can suitably commit to each other then love or no love, marriage or no marriage, you might just need to let each other go.

I hope you both achieve some peace with the situation.
