Interesting, the "IT'S NONE OF MY BUSINESS" thing sounds more like a gremlin to me. (And I don't even have gremlins on the brain very much these days.
Interesting enough, I know you worry about being delusional. But it's this thread that's sorta made me realize that it's not that you are delusional, it's that you delude yourself. Perhaps I'm the only one who reads this and thinks that telling yourself that your husbands sexuality is none of your business seems like an attempt to bury your head in the sand. If there's one thing that IS your business, it's your husband's desire for you and the intimacy that comes with that.
On the flip side, I'm glad that the angsty feelings have gone away. I hope that I'm wrong and that they stay away for good and that this is the start of something good.
