feel awful for saying this..I dont want to be pregnant

My ex boyfriend broke up with me recently and is now dating some whore that wanted him for years but she was in a relationship and now has five kids. I have been so upset lately and I just dont want to carry his child anymore but its too late ti have an abortion and even if I had the option I wouldnt do it because my emotions go back and forth constantly. I hate it! Im suffering not knowing how to cope, imagining him trying to sue for paternity and dealing with him for life! ugh I feel awful for not wanting this precious little baby he has nothing to do with this mess. Pregnancy is taking a toll on me emotionally
