I don't understand

I used to talk to a guy for the past at least three years , but recently I told him I'd rather not continue to play whatever game it is he's playing . for one I'm about to have a child and when I was carrying his he decided to stop talking to me and got a new girlfriend , resulting in a miscarriage due to stress . not to mention , he meant the a lot to me I honestly gave him more of me that I had , have , or will give to anyone . I always made sure he was taken care of and never asked him for anything in return . even when he got a girlfriend I still made sure he was ohkay . we are on good terms but I am nobody's ICE ( in case of emergencies ) girl . yet he blames me for having all the problems with my baby daddy because it's not him . I really don't understand how it's my fault when he decided and still chooses to play games with me when I honestly don't have the time for them .
