Dealing with a fickle significant other...help? ):

So my boyfriend is extremely supportive with what I'm trying to do with myself. He says he's happy I have goals and he's proud of what I lost; however, he did tell me that if I get visible abs he will not be with me because he thinks abs on a girl are gross and creepy. Now, it's obvious I'm going to have abs. That's a given. And I can't really change his mind on how he feels. If it freaks him out, it does. But is there a way that I can make it he can tolerate it? I don't want a 6 pack. I just want to be toned when I lose all of my weight.
