The truth is -- you really are grateful that your wife now has an FWB who lives so close -- although it does feel awkward for you when you see him when you and your wife take a walk around the neighborhood -- especially if the two of them start chatting and she then peels off for a quickie with him at his place while you continue your walk alone.

Your wife went to the reception alone, but she definitely wouldn't be leaving alone.
As soon as your wife's sister showed up for her annual visit, your wife couldn't wait to tell her all about her new boyfriend.
"The truth is, sweetie, that if I'd met him around the same time that I met you, I'm pretty sure he's the one I would have ended up with, and who knows -- if tonight goes well -- which I'm sure it will -- maybe eventually I WILL end up with him and not you."
