I just found out im pregnant im 4 weeks, me and him got into an argument really strong i said something i shouldnt nevr said but it came out i couldnt hold it i did apologize but he says hes hurt i know i was wrong for saying it but he doesnt have to act like this when all that happen i wasnt even with him, well the day after all this is when i found i was pregnant. Me thinking hes gonna be happy wronggggg he didnt say anything. And this past days i been crying i cant take this it hurts me knowing that he said hes not ready for a kid after it was him asking me for a baby he was the one who made me stop birth control. Now he says it happen so fast he does not know what to do hes confused blaming me for not using any protection when it was both of us who made th decision of having a baby im to the point of just leaving him 😭😭 hes so cold with me every time me or my other kids mention the baby its like he dont care. Right now i was trying to fix things with him joking around i said why he hated a baby that has no fault in coming into this world and hes answer was i dont hate him/her, what if it doesnt make it i was speechless all i did was turn around walked away and im in my room crying my eyes out 😭😭😭😭 why would u not want something that u wish for so bad. My baby has no fault in all this 💔💔💔 sorry for being so long i just wanted to vent i feel like shit honestly.
