Is alcohol really a truth serum?

Last night, my SO was drunk and was really mean to me. Some of the things he told me have crushed me. He told me he wasn't in love with me anymore and said that he was actually horny enough to fuck a fat pig like me. It went on for hours. This morning, he apologized. He keeps apologizing. We just decided last week to keep our baby. I'm 14 weeks pregnant. I don't feel there is any turning back now. Do you believe drunk people speak the truth? Or is he going through a mid life crisis like he says he is and really didn't mean those things? I feel abandoned. I feel like he really means those things deep down.. why else would he have said them? We weren't even fighting until he just started out of nowhere.
