Oh wow, he's an asshole.

What a pig, her fiancé that is

if it makes you feel better I'm pregnant too. last night dinner was salad with ranch dressing and waffles :(

That's funny, the only pig I see is him. Besides, everyone knows your nickname should be "Moo Moo".

Can I start calling you Wilbur?

Tell him you don't like the name and don't wish to be called after the sound farm animals make. However, on account you are willing to let this guy inseminate and marry you, I feel like this may be a case of hormones making you feel more sensitive than you would normally be. My sister, when pregnant, could not handle anyone making any sort of comment or joke about her. I said, "You look ready to pop" two days before she was due and she tried to punch me. Her boyfriend at the time said, "Babe, you look beautiful today." She burst into tears and said, "I am not a pig and I should look beautiful all the time." Your fiance has likely not changed in the time you have known him, so he has likely made jokes like this before. Either speak to him about the jokes or make them back at him. He should not call you a pig, but... it could be like when people call big guys "Tiny John" or tell skinny girls to "move your big ass." You know its not true, but you make a joke to show you care in a weird way.

thats okay when my wife was pregnant with twins she gave herself the nickname of pregie boss woddles.

What do you expect when you are pregnant and unmarried, prince charming?

I heard a lot of stupid things came out of people's mouths when they got pregnant. However, I always assumed it was the lady saying it.

OP, this was a misguided attempt at making light of the growing baby bump. When I was pregnant my boyfriend and I had great fun seeing how many different items we could balance on the gigantic portable table I was waddling around with. It's very likely that he meant no harm by it. If it actually bothers you, tell him you're self conscious about your weight gain and find his nickname hurtful. I bet if he knew it actually hurt your feelings, he'd stop. Or you smell like bacon. Or he's slightly evil.

Damn OP, you're marrying a five year old.

cut it down before it gets worse. that is absolutely no way to treat someone who's going to get bigger because of him. cut it down or prepare for a lot worse.
