I admire your strength. What you did isn’t easy and I give you so much credit!
I wouldn’t say that you “wait” as much as you kind of have to actively “normalize” and socialize your dad. I don’t know the guy, but I bet you he doesn’t have any close friends who are gay/queer… and even if he did, it’s something else when it’s your daughter. Things like this take time. Years. He just doesn’t know, you know? We fear what we don’t know. You have to help him to know.
I feel strongly that if my ex-girlfriend’s southern Baptist-raised parents from Virginia could come around to acceptance and a healthy relationship with their daughter, that anyone’s parents can! Okay, I am a little TOO optimistic sometimes, I admit. Still, I wouldn’t encourage anyone else to do something if I wasn’t confident that with patience, honesty, and courage that this will be fine. Or it will at least be okay. I fully 100% believe that.
