I wasn't making a statement, although I see nothing wrong with being a feminist or thinking women should be treated equally. My MIL said she was just going to call me by his last name anyway, which I found odd since she hates me. My thought process was more:
1. He fell in love with me. I'm not changing who I am or who we are as a couple.
2. My two degrees and all of my professional contacts are my name, not his.
3. I don't want to change all of the crap I have my name on.
4. My first name is boring, his last name is boring, and combined, there is a fictional character with that name.
5. My last name is much shorter and fits into those form boxes way better.
As for the kids, everyone knows they are mine, they came out of my body. We'll make sure he gets some credit too.
