Living with Teen Pregnancy

My name Lexi. I am 17 and exactly 5 months pregnant. The last 6 months of my life have been the worst that I have ever gone through. In december my parents got a divorced and in January I found out I was a month pregnant. I was mortified. I was the top Cross Country runner and set the 1 mile and 2 mile record at my school. I ranked in the top 1% of the runners in Texas and had scholarships like no other. Many were very for abortion. I had too great of a future. but I believed that its not the baby’s fault for the mistakes that I made. I was (and am) very much in love with the father. I honestly thought he was there for me and loved me. he told me he will be with me forever and help me through this. but through his friends I found out that he wanted to break up with me 2 weeks before he got me pregnant but he didnt have the guts to do it so he just stayed with me and got me pregnant. and the last five months he has been cheating on me. when I found out he dumped me and now exactly 2 weeks later he is dating the girl he cheated on me with and i get left behind to carry his child. I have never felt so alone, betrayed, and scared… I love him so much and I need him to help me. I know I need to just forget him and move on but we were together for 2 years and when I needed him the most, he leaves me. can anyone who has been through this help me? because everyone I know just dont know what to say besides that they are very sorry…
