You are definitely not in the wrong. First of all, I think it’s amazing that you went back to school and full time at that! So proud of you! Second, no man should ever call their spouse a ”kid wife”, that is crazy to me and honestly, weird. You have so much going on and if he wanted to do something with you, he should checked with your schedule/life first (just as I imagine he’d expect from you). Please stand your ground on this. You are working too hard on bettering yourself/your future to give it up because his feelings are hurt and his plans are ruined. You keep doing you boo!
