Husband made the worse joke! :-(

My husband thinks he is funny and is rarely serious. Sometimes he takes jokes to far and tonight was the worse. In 16w6d pregnant and I've only gained 2.5 pounds. I was in great shape when I got pregnant. I was trying to be romantic tonight cause I haven't been in the mood much lately so I lite candels and ran a warm bath (not hot.. Don't worry). I called him into the bathroom and asked him to take a bath with me. We have a huge jacuzzi bath. He said "I'm not getting in that bath tub with you! Your the size of a beached whale and we would get stuck." He started laughing at his "joke" and I burst into tears. I'm so pissed. Afterwards he kept apologizing over and over but it's not making it better. I'm having a hard time with the changes already. I didn't need any help. :-( he owes me!
