<human>: My boyfriend and I have been together for 4 years since we met in high school.  Though we've had our ups and downs I am certain he's the one for me; however I have a small problem:

I'm worried our relationship has become a bit stagnant. He and I are both in college (same university) so I realize it's difficult for us to take the next natural steps in a relationship as we are so young. I've found myself desperately longing for an engagement. I firmly believe (as does he) that we are to young for marriage and that we'd prefer to wait until we have graduated and hopefully begun careers. So I'm not wanting the wedding, I guess I just want to feel like our relationship is growing into adulthood with us.

Unfortunately we can not live together or even vacation together as his parents are extremely traditional and wouldn't approve of such things until we're married. While I hate his parents having so much say in our relationship I have to respect this. His parents are funding his school and he has a close relationship with his parents he doesn't want to tarnish,  I prefer to support that relationship rather than compromise it. His parents have always been very kind and supportive of me and our relationship. They just have their (in my opinion) outdated views. 

So my question is: how do I make this relationship feel like it's maturing and progressing without taking big steps such as engagement or cohabitation. Sometimes I feel as though our relationship might be somewhat stuck in high school.

Summarize the given text in a few sentences.
<bot>: How do I make my 4 year relationship feel like it's progressing without taking big steps we are not in position to take due to age and family.
