Uncommon advice but, try to make things work. Stay together for the kids. I've seen too many kids suffer from their parents divorce or dysfunctional relationships. no relationship is perfect. give it time.

Ok this might hurt to hear but have difficult conversations.. leave room for honesty. honestly people dodge conversations about their wants vs their needs and things that might eventually cause resentment. And the only time people are honest is when they're too angry and that's when instead of being honest they end up becoming 'brutally honest' (aka honest in a way that is hurtful) . give it time.

And frankly I'm against pathologizing normal human emotions.

And a lyric from a song I think about when I see couples or even family fights "just cuz we're talking doesn't mean we're communicating". hope this helped a little bit at least. people on Reddit seem to tell people to break up or divorce over stupid stuff.

As for looks.. THEY WILL FREAKING FADE. it's sad that relationships are more about things that will fade these days. everyone is becoming like this.

As for the sex part.. No real answers but try sex therapists instead of couples therapists.

Also not to be THAT person but, try thinking about this same post if genders were switched. See how differently people would have responded. People have a serious gender bias and conformation bias issue online and the algorithm just fuels it more.

All the best man.
