Knowing how much you love it, I'd stick with it. If you pronounce it Ev-a (Ever) to family and friends then they'll get it right surely? Are you happy with this pronounciation or do you prefer Ee-va? If so, then that might be a problem if you and DH can't agree.

If it's misprounounced at mother's group, school etc who really cares? You'll/she'll either correct them or not?

Why are men so stubborn about names
