This is a very common scenario. More often than not your friend understands love comes before (platonic) friendship. In fact very often when we start dating someone we tend to spend less time with friends we intend to maintain friendships with.
Ultimately there is no "right" or "wrong". There is only "agree" or "disagree" instead of you trying to convince your mate to accept your friendship or your mate trying to convince you to end your friendship you'd both be happier if you found other mates who (naturally) accepted your desires. We're entitled to have our own "deal breakers".
Love is about accepting people for who they (are) and the "perceived baggage" that comes with them. If you can't do that then it's best to move on. If it were me I'd wish my mate the best of luck.
