So now my ex is around me everyday I mean we are going to sleep together waking uo together, having ..you name it we done it. this has been going on for seven months. I just found out that I am six weeks pregnant, and he is saying that he is not ready for the baby because he can barely afford to feed his self. I feel like he is saying this because she is to be released from jail next tuesday, and he don't know how he can explain this situation to her. I am devistated. I feel like he is putting a female before his own flesh and blood. saying he can barely feed his self, but yet you are about to take on the responsibilty of taking care of a adult, who is not going to be able to work, because she is a convicted felon. Please help me, So I can start my healing process and move on from this nightmare.
