He's using you just like most men and women that decide their OH's with their cheating, lying and deception
You want "control"?? Well, consider this. Use the deceiver, complete your studies, line up a job, save money secretly, find a lover, then LEAVE. I bet you if you did that, he'd be in shock
A work friend of mine, not close but a friend, he told me/us that he left his wife and told us why, ie she was a cheat and had several one night stands. He was a broken man the 1st/2nd time around took time off sick. However, he decided to play her and found a new love on a dating site, the lady was divorced and then one day when his wife was away for the night on a work-related thing - he took his share of the stuff and left. The apartment was rented..
The man's wife, did she cry, she cried like a baby blaming her husband for cheating and leaving her "homeless " as she could not afford the rent/bills on one wage, lol.
So teach him a lesson on what it feels like to be treated like that
