Have name changed as this may be identifying.
Me and XP have 2 DCs, we had DS1 quite young, and split after years together, we were apart for about 6 months then got back together (stupidly but I believed all his "I have changed"), I fell pregnant as a contraceptive failure but he said he was happy for the new baby etc. DS2 was born and we split again when he was 6 months as his old emotionally abuse ways returned. DS2 is now 3 and we have been co parenting amicably considering.
I have had a message from an old flame of his, telling me her DD (5 years old) is his, as a result of a brief fling when we had split, she said he was made aware of this when she found out she was pregnant but has denyed its his as she was promiscuous at the time. I feel heartbroken and in shock that our second relationship was a sham really on the back of this big secret and now and don't know what to do next.
Ex says she told him there was a chance he was the father but he didn't believe her and she refused a DNA. He now says he doesn't have the money for a DNA so I expect he knows theres a fair chance its his. What do I do??
