Feel alone

I never had a big group of friends, always just kept the real good ones close. When I moved to the USA to start university, my main fear was making friends. But I did. My roommate being my best friend. All of a sudden I went from being not that popular to very popular. But then a while bunch of stupid girl drama hit the fan and I no longer talk to any of those girls. St the start of my second year I moved in with my boyfriend (off campus). Now Im just having a hard time finding friends again. I try to talk to the people in my classes, but it just feels like they dont really care to take the convo outside the classroom. Or that they already have their clique and are not looking to expand it. Ive been told girls find me intimidating and so they dont ever try to talk to me. Ive been trying to be less intimidating. I just dont know what to do. My boyfriend is my best friend, but I crave that girl talk...ya know?
