What should I say to this girl?

"Hey, long time no talk.." Don't try and act to awkward just be regular and if she reply's then great if she doesn't then **** her.

Tell her you two should get back to where you left off when you were happy together ;) lol jk Be cool with her and talk and if things go good try to either date again or hook up or at least stay friends with her if she means that much to you. If she hates you or acts like a ***** after 2 years screw her and just delete her and get rid of her...you don't need negative people or people who have a grudge against you in your life.

Just don't, I got a friend request from one of my ex's and I flipped the **** out on him. If you didn't leave the relationship in good shape, then DON'T TALK TO HER.

Just say "hi" or something generic. It doesn't need to be anything special.

If you still have feelings for her then do what that guy said vvvvv. If not then $crew it.

hey, I hope lifes going well, what have you been up to?

don't bring up any current realtionships.
