Try to relax about making friends and change your focus. (I have known several couples in my lifetime who tried and tried to get pregnant, they gave up, started the process to adopt, and in all cases ended up with two children very close in age). I’m not suggesting that you give up, just dig deeper into something else available at your campus to focus on ( your academics, research, theater, walking, running, whatever) and let go of the press to make friends. Stay open though and be prepared for the fact that you may meet someone at the most unexpected time or place. This is true of all life’s relationships, not just those in college.
