From my anecdotal experience, being out of your comfort zone is the actual highway to relationships.
I used to live in a house in a foreign country to which people from my home country crashed to during their short, usually few week visits at the area. Surprisingly, the people who came there were exceptionally open (exceptional as in compared to a usual native). Most of them came either alone or with one friend/business partner. I think a lot of their openness attributed to the fact that they were in a temporary, new environment.
I also noticed that being open myself first helped to initiate deep conversations. But after returning to home and to college, despite continuing to prompt these discussions, I rarely get the same kind of reaction anymore.
My general observation is that my peers are happy to answer questions I have, but they lack the social skills to listen and ask leading questions. But then again, this might just be that they find me uninteresting as a person, but the difference is worryingly stark -- out of 30 people I've befriended on Facebook only a few have I had conversations deep enough I'd consider to meet up with them just to talk. The numbers were very much the opposite if you'd compare it to the experience in the foreign land.
Thus, I think it is silly to have fear of missing out on relationships or a partner during college. With the new brave world of remote working, I could as well make a living in the opposite end of the planet just a mere day after graduation, to which I am quite sure most of the peers won't (or wouldn't) follow me anyway.
