Your Daddy is married. You and his wife are metamours. Sometimes metamours get along great and become friends. Occasionally they become lovers. Quite often there is neutral or negative feelings and all one can have is politeness and respect without friendship.
So, just because you are bi curious doesn't mean she is the right woman for you and vice versa. If Daddy allows it, you can meet her and see if you get along, and take it from there. Keep expectations low if possible until then.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
