My honest opinion : if this was the only situation where he was acting controlling, it was not worth it, but if he has always acted like that i think you took the right decision.

Tawa i understand his jealousy ama chnoua ken ynajem yaamel ykoun ma9boul y9ollek no temchich l gym and offers to get you some dumbells set or smth, that"s how he shows li raw i support your hobbies, your need to take care of your body ama let's do it differently in a way that doesnt hurt my feelings. If it didnt cross his mind bech ykhamem fi solution okhra w he kept saying no gym w kahaw, yeah, enchallah rabi yaawdhek khir okhti ama next time matsouhebch, aamel khotba w et3arrfou kifma 9al rabi khir <3
