Yep... He sided with himself.. He isnt' leaving you for his parents.. he's just not grown up yet my dear...

THe question is how much coddling and dead weight are you willing to take into a marriage?

I am not saying give up on him, but I would stay separate untli you can see he can self-manage...

Right now he's still a child... He never let go of his parents, he never learned to self-manage.. He runs to them whenever he's in crisis... Children do that... not adults
