tiff200710

ok so we had our first appointment yesterday and im 13ish weeks and he was there and saw and heard it. everything was going fine. this morning he texted me and asked if i would be mad if he dated- since we were not together anyway i said no but i said i hurt becuase we didnt date because he "wasnt ready". so then he said well i didnt want you to find ouf from facebook... which im not on ... so they are already dating.. so now i am up set and I dont know what to do. I was trying to work with him on everything now i dont want him near me or to even come to the appoinments with me. am i over reacting? I am just hurt and want to hurt him anyway i can- and he says he doesnt want me telling people he is the father but screw that... he messed up and now i feel like i want to make him hurt like he just hurt me. any advice?
