This is going to read harshly. Feel free to skip.
Why are you remaining in a marriage that appears to be no longer working? If there is no emotional, sexual, or romantic connection with your wife, why are you still in the relationship? You two can raise your children and still be good friends who love each other without being married to each other.
Why are you having sex with women you like, even love, but you don't find attractive? Some of your other threads mentioned this pattern - sex with women who aren't actually attractive to you. I don't get why you can't just say 'No thanks. You're awesome but I am not interested.'
It does sound like you need to be single, to figure out who you are, what you want and who you truly feel attracted to and want.
