me and my now ex boyfriend had been dating for awhile and we were super close and everything. he was the thirst guy I made out with and I was head over heels for him. but going into highschool, I didn't want a boy to complicate my future. keep in mind this boy didn't plan on having a girlfriends in the first place, he didn't plan on marrying in the future and didn't want kids which was completely the opposite of me me. we just had different goals. anyway besides the point I knew my best friend was talking to him as we were dating and I began to think she had feeling for him. so I just shrugged it off. later after him and I broke up there had been some talk. so natuarally I asked her about it and she said it wasn't true and that she didn't like him like that. so I believed her. yesterday I found out that she had been lying to me this entire time and they're talking and both like each other. I wouldn't be as mad at her as I am if she would have just told me the truth, I'm I wrong to be upset?
