Thank you all for your replies.
We started talking about opening up the marriage a year and a half ago. I had fallen in love with someone else, but didn't act upon it. It was the trigger to start talking, though.
We do talk everything through, but I had a hard time getting the courage to discuss this in particular (I only could this afternoon). It's tough to tell this to someone you love, you know. But we ended up reading your replies together, and it was good.
You're so right, nycindie! Still, it was so much easier for both of us to accept the ebbs and flows of desire before opening up the marriage
It was reassuring to know that NRE can do this to your libido
. I won't take any drastic decision right now. We'll spend some more quality time together and see what happens.
Thanks for the support!
