<human>: Not a throwaway account.  Don't even care if she reads it.  Nothing's here that she doesn't already know.

We've been dating for over a year and recently had a break up.  We both knew it was coming due to a handful of incompatibilities mostly related to incomparable sex drives.  We had just seen each other for two weeks during a winter break.  The next day we broke up over a Skype text chat.

The next week she had casual sex with her friend.  I don't like him.  I fucking *lothe* him.  While I was overseas for an internship, he tried to coerce her into cheating on me.  He's fucking her now.  And even though I know that the relationship simply ran its course and he was simply available at the moment, it feels like she left me to fuck him.  At first I didn't care, but it's been eating at me slowly.  This is the first time I have ever experienced jealousy.

Other than that, I have a feeling of emptiness.  Some people do better on their own, but I need companionship- I always have.  They help me grow and become a better person.  They give me desire to work and give purpose to leisure.  Without them, I feel stagnant.  I hate that feeling.  It makes me feel empty.

The only solution I can imagine to soothe this is to start dating again, but I'm afraid I'll fall into a typical 'lonely guy' trap of dating the first person to flirt with me instead of someone I actually want out of fear of rejection.  I fear that if I wait it out too long, this last semester of college will be over and I'll have no one.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: The break up was nice, but the aftermath has caused intense jealousy and lonely depression/anxiety.  How do I release all this stress in a healthy way?
