found out my husband

Found out my husband has been texting his ex saying that he wishes he never married me and nothing competes with her. I confronted him and he said he was drunk and they don't mean anything even though the dates on the messages are weeks apart. Somehow he found a way to twist it on me and I ended up apologizing at the end of the night. I don't know what to do, we have a 2 year old and one on the way 😞
