My wife and I have been open for about 2 years, and about a month and a half ago I met a girl who I started seeing and had some chronic NRE with.. skipping all the details, she let me know over the weekend that she had started dating someone and wanted to be exclusive with him, and my heart sank. Of course, I didn't let any of this on and was totally respectful of the new boundaries she wanted as we still run into each other every now and then, but this is the first time since we opened that I feel like I've been broken up with. I know I'll be over it soon and it was just a short relationship, but holy cow does it sting.

The difference between this and regular breakups is that I feel totally isolated. I spoke to one friend who absolutely didn't get it - which is not her fault at all, but definitely feeling the lack of support as a result.
