Had a bf we been going out 4 5years. Got pregnant. As my due date draws near found out that his gf he had b4 me was also pregnant an she says its his. He says that he wants me an what happend between thm was a mistake an although they slept 2gether he is sure tht the baby isnt his,bear in mind thy already hav a son 2gether. How can sum1 b so cruel?
