If this happened to you, what would you do?

Alright, for my question, see the title. Here’s details: A month or so ago, I broke up with my boyfriend because I knew he still liked my good friend… I’ll use a fake name for her: Orihime (She loves this charater) and a fake name for my ex-boyfriend: Kiba (loves this character as well). When I had asked him about it he got all nervous and started saying “I swear! I don’t I don’t! I swear! Did Mixea tell you? I used to like her, but I don’t anymore! I SWEAR! Please believe me!” I told him I did. I lied. I can read the boy like a book >>.>> I broke up with him four days later. After we talked about it a little bit he asked me if it was okay if he asked her out!!! THE NERVE OF THE BOY! I told him it was okay, and I didn’t mind. That infact, the reason I broke up with him was to make him be able to be happy… I didn’t want him to ask her out, I wanted him to come back to me and try to earn my respect back, but he didn’t. I did want him to be happy and I did do it to make him happy mostly, but I also wanted… want him back!

A few days later I told Orihime that I broke up with Kiba. When she asked why, I told her that it was because he still liked another girl while we were dating. She called him a bastard and asked who it was. I didn’t want to tell her, but she wouldn’t stop asking. I told her it might be a shock, but she still wanted to know. I told her it was her. She was very surpirsed. She told me that she didn’t want to go out with him and if he asked that she would refuse. She said she wouldn’t ever date her friend’s ex.

Two weeks later, Kiba asked out Orihime. She said yes. They’ve been going out for a shorter time than he and I did and they’ve had their first kiss together… in front of me. I’ve never been kissed (besides my family. You know family kisses --) and it makes me very depressed sometimes. I still like him, but I wouldn’t try to seperate them. No one seems to object to their relationship, though they should since Orhime says to me that I’m her sister all the time -- I still put on a happy face when I see them and I act like it’s all okay. I tell them that I’m happy for them, and I am, but I also am super jealous. They still act like my friends, but sometimes I just want to slap Orihime across the face and pull Kiba into a kiss in front of her and see how she thinks it feels! What the heck am I supposed to do? It’s not fair for them to hurt me like this, right? Or am I just being stupid and need to let it all go?
