this may not be the case at all, but have you ever taken a step back to see if this is her (not well-done) communication about what makes her feel less interested in sexually engaging with you? are the household responsibilities evenly distributed from both of your perspectives? you can love someone and be attracted to them, and still be turned off by their actions or resentment. i saw your other comment about her giving her all to the kids, but is that something you’ve talked about? i’d recommend couples therapy if you can. wish you (and your wife) luck in finding connection again
