<human>: Can you provide a brief overview of the text?

My girlfriend broke up with me over text on my drive home from class today. We had conflicting views on the topic of sex. I wanted it, but she couldn't decide if she did. She would lead me on and back out at the last minute and then tell me I wasn't respecting her decisions (can elaborate if asked).

I'm half way through my first semester of college and (me being an introvert) haven't made many (any) friends yet. My old group of friends were mostly younger than me and I only really saw them at homeschool events, which I no longer attend.

I could tell my old friendships were fading and I could feel the distance between my girlfriend and I growing. I understand that friendships rarely last a lifetime and I think I've come to terms with my girlfriend breaking up with me, we're still "friends". I knew she wasn't the one I was going to marry, and I knew it wouldn't last much longer (she's moving soon), but it still hurts.

My problem is that with my girlfriend breaking up with me and my friends fading away, I'm left with too much time and an emptiness inside that none of my hobbies can fill. I don't know what to do with myself. I feel alone and afraid of getting too close to anyone for fear of being left alone again.
<bot>: Girlfriend broke up with me. Friends faded away. Feel empty inside. Hobbies aren't enough to fill emptiness. Difficulty making new friends.
