Hey RDJ, I'm interested to know your own headspace around your relationship with your wife. I've seen you mention that she is happier with the time you're spending together, but what about yourself? How is spending time with her for you? How do you actually feel about her? You've mentioned that she is "hot", but that's more a statement of how you think the world sees her, but is that how you actually feel when you look at her?
It seems to me like there might be problems in your relationship that aren't being acknowledged. Keep in mind that you might not be alone in this: even though she seems happier, and she's starting to initiate sex with you again, doesn't mean that it's all fine and dandy on her side. She might be worried too, and trying to get things back on track with you by trying to be normal and enthusiastic. But it's very rare that one person in a relationship is totally happy while the other is feeling strange about it. I think you both might need to have some honest conversations about what's working and not working in your relationship. I know this is a tricky subject because you have alluded to your wife having a delicate state of mind recently, but it sounds like it's taken its toll on you - maybe this is what's changed your attraction to your wife? Maybe you view her more with concern and worry now more than interest and fascination. Domestic life can do that. It's not easy to maintain an illusion when harsh reality keeps poking you in the eye. Once a relationship gets to that stage, the illusion can't be rebuilt, so the only way through is to move to a deeper connection, with more communication, more intimacy. This can reignite the sexual flame if it's done properly. But in my experience, once you feel that "nothing" feeling, it doesn't get better unless you get closer and change some things about the way you talk and what you talk about. Keeping things the same doesn't increase attraction. In fact, these situations become intolerable after a while because you feel like sex with your own wife is a disgusting prospect.
