I'm thinking of potentially starting a relationship with a girl as a second option to my first.
What is your first option?
My first option is to leave my girlfriend who makes me unhappy.
If you're already in a relationship, it's wrong to cheat. You shouldn't do that to your partner. You should be honest.
Fuck! My girlfriend cheated on me with a guy who is a year younger than her. My second option was a real option and I think she is a slut.
You need to at least end the relationship first or the second one will start off on the wrong foot as well.
