My relationship with my boyfriend is making me feel boxed in. I just want to run away.
What's he doing to make you want to run away?
He's very strict with me. I can't really express myself, especially about boys.
If your boyfriend is behaving in an unreasonable manner, then it is a good idea to leave him. Partners with excessive rules can tend to be abusive, so it is best to leave those kinds of situations.
It's good to have someone love you and be strict on you every now and them. It'll make you a better person.
It's OK to discuss expectations partner's have of each other, but not when it turns into a list of rules and obligations. You're a grown woman. You don't need a strict parent; you need an partner who respects your individuality and treats you as an equal.
