Based on the question and the responses, it seems to me, that some people are lacking in the belief, (emunah), that all matches are made by G-d, everything is bashert; do you really think you can “allow or disallow” your child from marrying their bashert?? Most often, the parents who interfere with G-d’s plan, live to regret their actions. As long as neither side is compromising halacha by the choice, there should be no issue at all.
