The sad thing is the power of love thing does make sense.

Zeref didn't appreciate the sanctity of life when trying to revive Natsu so he was cursed.

Zeref through love learns to appreciate the sanctity of life therefore lifting the curse.

The thing is this was not done well so this was not quite the result. We are lead to believe Zeref loved Mavis the first go around and Mavis only fell into some kind of coma. If anything that means he really didn't love her and also how do you love each other now after all the crap and betrayal you all went through while being separate for hundreds of years.
