A buddy's ex-girlfriend is getting married.

Your ex-girlfriend is getting married, and you feel very sad. It is because you still miss her and love her that you feel uncomfortable. But he's already your ex, which means you already have a girlfriend. I don't think you should do both! You should bury this feeling directly in your heart, never let it show, and give you all your enthusiasm. Now, my girlfriend, I don't think you will be sad.
