Had a terrible weekend, can i have some compliments?

[Time Lady]

Found out while I was dating someone for 2 years they cheated on me. All the sudden they just started ignoring me and then I found out through facebook he had deleted me. His profile picture was of him and a girl from his new school hugging. His wall was covered in posts from her saying how much she loved him and how great it was going out with him. All posted while he told me he loved me and would never leave me. He chose a girl he has known for a week over a girl he knew for years, and dated for 2. He didn't even tell me there was someone else, he just left. I feel terrible and insignificant and tiny. Can you guys cheer me up?
Omg, thank you, all of you. I'm truly moved by all of your touching words. I appreciate it so much, this is what I need to hear right now.
