<human>: Condense the text into a few key points

We both just entered our first year of college together. We have been dating for 3 years currently and 5 and 1/2 years total. She meant everything to me. 
We broke up because I got jealous about her being around other guys and hanging with them. She got defensive. I was stupid. I should have realized that she just wanted friends and not to be stuck with me all the time. 
I spoke to her dad about this and he thinks I should give her some space and wait for her to realize she wants to be with me, but I worry she won't.
Now she wants nothing to do with me and wants me to leave her alone. I don't want to be without her though since she means the world to me... 

I don't know what to do.. I don't feel motivated to do anything. I just want her back. I love her.
<bot>: I lost the love of my life because I got jealous. She doesn't want anything to do with me. I screwed up and I don't know what to do..
