It was my Senior year in High School, I was so glad that I was finally a senior and getting ready to be done with school for ever. I had hopes that I would maybe meet the man of my dreams that year, it was about 2 weeks after school had started that year and I walked into gym class and I hit it off with this guy i'd just met, we was playing tennis that day.. and I didn't have someone to play with so he asked me did I want to be his tennis partner. We talked all that week, and then it was a few days later he asked me out. And we hit it off very well...I really did care for this guy, and was getting close to him fast. Well we dated for about 5 months and then out of no where he ended our relationship, he said that he had only dated me because he knew I was popular at school, and because I was considered one fo the pretty girls at the school and he thought he would get popular if he had a 'hot" girlfriend...soo at this point I was hurt and mad at the same time...well we broke up, and then about a week later he calls me up and is like I didn't mean any of what I said when I broke up with you. He said that he's little sister that was 13 told him he should break up with me...because I was to preppy and she thought I was snotty...well this really made me upset...and I didn't know if i should take him back or not, I hesitated to even consider takeing him back after this.. but of course I did cause I was stupid and just ignored the fact they he broke my heart once and all that because I loved him and wanted to be with him so i took him back. Well we dated for about 5 months after we got back together the second time...and we got along pretty well and things went okay, and then things started not going good again he was kinda acting as if he was gonna break it off with me again and just stuff like that soo about 3 weeks ago I just ended it with him, and told him I thought we should maybe take a break for awhile.. soo we did. But we said we wouldnt date other people until we knew for sure if we was gonna break up for good or just take a little break and get back together soon, well he came over a few days later and we acted just as if we was dateing still and we made out and stuff..and he told me he loved me still. Well later on that day after he left my house I tried calling him and his cell phone was turned off...soo that night I got online and I was looking at his myspace and I saw this girl was his number one friend...and she left him a comment that said hey i had a good time on our date tonight... Soo then I had seen that she had sent him some more messages earlier before that one.. and the first thing that run through my mind he had cheated on me while we was together cause we hadn't been broke up long. Well I called him and asked him about it, and I said Did you cheat on me? he said no amy i didn't he was like I met her on myspace and we just started talking he was like I've known her for awhile..he said she wanted to date me a long time ago but me and you was dateing so I told her i had a girlfriend.. so then I was like so you talk to her while we was still dateing? he said yeah every now and then but not nothing like that...I was like well...you got over me fast... he said well amy i was lonely and wanted  to be with someone so I dated her. Then today he got online, and we was kinda talking a little bit....and I ask him I said Nick i want to ask you something and be honest with me, he was like okay what is it? I said did you cheat on me with her? ever..he said No i dont cheat i've told u that...I was like well.. he said Shay my sister got me and her hooked up amy.. i said what!? I said your sister did...he said yeah.. cause I was lonely and wanted someone.. I said why didnt u come to me? and then he was like I dont know amy I dont love you no more I love her..and i dont know he says he didnt cheat on me but I think it all was just weird cause they got together in the same day he came here...but I just want some advice about this situation....cause I feel like i've been replaced and that he cheated on me but he says he didnt..but I just for some reason think he did....
