Ex-girlfriend

By chance I met my ex-girlfriend in Portugal.

I'm getting back together with my ex-girlfriend.

Actually, Mary is now my ex-girlfriend.

You're not as beautiful as my ex-girlfriend, but you're a lot more fun to hang out with.

Seriously, I postulate that I am, right after my ex-girlfriend leaves my house, going to talk to myself in Lojban.

This is Mary, my ex-girlfriend.

Mary is my ex-girlfriend.

Tom sat across from Mary, his ex-girlfriend.

Yesterday, I was on my way home when I unexpectedly met my ex-girlfriend.

Mary was upset when she saw a picture of Tom's ex-girlfriend in his wallet.
