Keep in mind that you're not the only girl he's texting nonstop.
You're not the only girl he calls "babe."
You're not the only girl who holds his hand.
You're not the only girl he sends good morning texts to.
You're not the only girl he likes.
You're not the only girl he says "I Love You" to.
You're not the only girl who meets his family.
You're not the only girl he writes letters to.
You're not the only girl he goes out with.
You're not the only girl he cares about.
You're not the only girl who loves him.
You're not the only girl who feels like you can't live without him.
You're not the only girl who's with him.
You never were.
You never will be.

I had to learn that the hard way.

Get out while you can
It'll only get worse.
