Serial monogamist 

A serial monogamist ~ a person who loves being in love, and always finds him or herself in relationships all the time. Being a serial monogamist has its pros and cons. On one hand you’re monogamous, you would never ever cheat on a partner, and no one likes infidelity. They do NOT go from one person straight to the next. The time span is not limited

I’m a serial monogamist I just can’t be alone :(
