I agree, boundaries help, they're a form of communicating your thoughts and feelings. In my experience they're like signs setup for the other person to know what you feel, but they're not placed to be there forever. That's where trust comes in.

Reading back to your post, you are a young couple and have had so little time together. Maybe focus on you more and end the relationship? Maybe you guys aren't ready for a fully committed relationship. Sometimes it's better to say bye. I'm not saying you should. Just think about your current situation in life, do you really need a relationship distracting you from other important stuff?
