1)I abjure my love of you!
2)I abjure my love for you!
The first one is given as an example for the word "abjure". However, so far, I have seen only "love for you" to mean "the love I have for you" but I haven't seen something like the first one. Is it common?
Either would be acceptable, but I don't see how anyone can abjure love. You can abjure a right or a practice, or a claim, or an aspiration or..., but if you love something or someone that's the way it is. You can swear not to do anything about that love, but what you're abjuring is not love.
