If I’m dating you, you don’t need to get jealous of other people. I am with you, only you. If you ever think I’m flirting with other people, I’m not. There’s a reason why I chose you and only you. I only want you, no one else. You are mine. I am yours.
In college, we don’t say “I love you”, we say “I have 5 essays, two finals, and 3 group projects due in the next 8 days” which translates to “I would like to be crushed by a train” and I think that’s pretty cool.
