Ex wont give our baby my last name.should I change my last name to match our baby?

Very early into our relationship we found out we were pregnant. Though things went well at first, we've since broken up. Our daughter will be born in two months. My ex was very clear "we are not friends, we are not amicable, we are co-parents, I will be civil, nothing more". I've stayed involved throughout the pregnancy though. This is my first/only child. She is dead set that she will give our daughter her last name and not mine. So, my question is, is it a good idea to change MY last name (which I dont really have a fondness for) to match what my daughters last name will be? Or will this likely just piss off baby mamma??
