I hope they don't get married period. Jellal is a waste of space, hope he snuffs it.And? Since when does it matter who you're trained by? Ultear was trained by Hades but got beat by Gray. Hades was "trained by Zeref himself" but got his ass kicked by Natsu after he ate Laxus' lightning. If you're not stronger than somebody, you're not stronger. End of story. Him not being able to break it makes absolute zero sense. Everything about Jellal is terrible, including his weak plot line.
I pointed out that it wasn't a matter of magical strength, but a psychological problem on Jellal's part. The brainwashing wouldn't have happened if he wasn't mentally vulnerable to begin with. It's the same thing how extremists/rapists control their people. They take advantage of their victims' psychological vulnerability to control them.
Once they have gotten their grips on their victims, it is rare for them to escape it.
