How do I get over my first real boyfriend?

It all started when my friend called me and was talking about his girlfriend. just outa of nowhere I told him that I liked him alittle. But as the call went on…it got worse! Ya see, Im one of those people who cant hide anything from someone. So if I think I done something wrong, I had to go tell my boyfriend. Well my friend wanted me to have phone sex with him. Well I was like I love my boyfriend and I dont think he would approve of this NO NO NO NO NO NO NO!!! so he got mad and started saying crapp about my x. So I changed the subject on him so he would stop talking about it. The next day, I told my x about what happened the night before. He got mad and just started going off. All he herd was that my friend wanted me to do the phone nasty and I stayed on the phone. But before I could even tell him nothing happened, He was like I really dont want to date someone like you Brittany!.. IT broke my heart in to. Ya know that song Over you…that tells it all or even WHo Knew by Pink! That works too! But now that hes gone…I really want him back! He was my first boyfriend and I had a lot of my firsts with him..Ya no what I mean??? But I just wanted to know if someone out here could help this broken hearted teen with her broken hearted problems!
