Since Jean is the one who screwed Eren up, yet Jean is shown not being an assertive person (following the seniors/ going along with sex/ going to get a drink because of friend pressure) Jean is making it up to Eren the best way he knows how. Instead of Eren going everywhere and barely surviving as a sex/drug junkie, Jean decides to keep him and simply sate Erens desires but protect him as best he can.
which leads to a fucked up relationship with heavy power imbalances (bc jean provides everything) where eren only asserts power through emotional manipulation and weird bouts of passionate rage. signified by how hes tied up like a dog.
