Broken Hearted

It is the night before the 19th Birthday and Im laying on the couch with my boyfriend who I am happy in love with and all the sudden my ring tone for a text message goes off. I look at the time and there is still 15 minutes before my birthday. So I look at the text and it was my x-boyfriend who was also the first guy I said Im in LOVE with you to. I look at the text with my boyfriend over my shoulder and I tell him to back off because this message looked mean.The text was all negative things about how he hated me and Im the dumbest person for choosing my current boyfriend over him. I broke down and walked into the other room and called my best friend. She completely gets me, unfortunatly nobody on here does so I need to explain it to all of you. My x was the first guy I truely loved and who I fully gave my heart to. He betrayed me by having sex with another girl and getting her pregnant. Then he came home and acted like everything was amazing with us, meanwhile he completely knew that the other girl was pregnant. I got mad and retailiated by cheating on him with another guy. We had a very bad break up but we still tried to remain friends. About 8 months ago I met my current boyfriend and I was unsure that I wanted to be in a relationship, but that did not matter to him. He waited for me for 6 months until I was ready to be with him. He is the best thing that has ever happened to me and I full heartedly know with all my heart mind and soul that I love him and I know that we can conquer all. SO back to what happened tonight. As I was on the phone with my best friend my boyfriend came over and held me while I was crying to her. He has no idea what is going on except the fact that my x had texted me. As my girl and I started talking deep, I asked him to leave and I got mad and pushed him away. I have this hard exterior when I am upset because I dont want people to see me upset or hurting, so when my boyfriend wanted to be there I didt know what else to do but push him away....I dont feel like I made a bad decision by choosing my current boyfriend over my x, but I do wish he would either leave me alone or try to be my friend. I dont want to sit here and cry on my birthday. I dont want to remember my day like this.....
