I wish you the best in your relationship. All relationships start with "monthversaries", when they can't celebrate anniversaries yet. If she is strong enough to resist her family opposition, you two will get the chance to celebrate many anniversaries.
Most AGRs create some sort of opposition if not from family, from friends, but when there is love, that will not matter. Honestly, I rather have a partner that encourages me to fight for our relationship, than to tell me that he wants no problems, because that means that there is also commitment on his part, meaning that if I am willing to fight, he has to be willing to commit. In other words, if he is not willing to commit, he may think that fighting with family is not worth it.
