So me and my boyfriend have been together off and on for 3 and a half years,during that time we were dating other people,the last girl that he dated is now claiming to be pregnant by him while I'm pregnant by him,she says she's due in August while I'm due in December. She is very aggy and crazy,she lied the first time about being pregnant by him and this time nobody knows if she's lying again I'm just ready to find out the truth. I really want to beat her ass though,but she's not worth it. Any advice
