She most definelty can be going through MLC. My 29 year old W is too. My sitch is attached at bottom if you want to take a look. Funny, my wife got into fitness real strong and also is "friends" with an older man. Funny how that works. You should keep reading all you can here, keep up the PMA and vent whenever you need to.
Also check out user "trapt" posts, his young wife is going through this too. We all need to band together and stay strong.
Good luck we are here for you.
