I don't want to turn this to myself, but I just can't help but think about my own situation while reading about yours (and others that have posted in response).

If you have a healthy relationship with your partner, where everything else is "perfect", or at least nearly so, then it depends on how much this lifestyle outweighs all of those other positives.

A lot of the time that I think about my own relationship, I feel neglected. I constantly worry that I am annoying him somehow or that I will piss him off. There are a lot of angles to look at my current relationship, and then you add the fact that he seems to of lost interest in the D/s portion. I don't know what is going on in his head, but even as much as we have talked about it I still feel the same in the end. I'm not sure if I won't end it because I'm afraid of losing everything or because I really think he's "the one"...

Honestly, it comes down to how you feel, what you are willing to give and take. There is a lot of good advice above that I think will help you...Though others have offered it, feel free to PM me any time to talk, about this or anything else...
