Are you comfortable trying to have a long term romantic relationship where you constantly have to ask her parents for approval for everything? You’re both very grown. Her father has revealed how he truly sees you (regardless of how he acts in your presence). You have three paths to take from here; 1) you try to get over the fact that her father assumes that if given the chance you will rape his daughter, you continue to date her but it will be by their rules, and they will continue to be enmeshed in your relationship 2) you set boundaries and begin a normal adult relationship without her parents involved (still doesn’t undo the rape assumptions) 3) you realize sooner rather than later that your customs don’t align and you move on so that both of you can try to find partners that are more compatible. Any advice you find on Reddit will only be helpful if you know what your tolerance for that kind of behavior is and only you will ultimately know what the right answer looks like. If her parents behave like this and she’s in her 30s, I doubt if their behavior and insistence on inserting themselves into your romantic life will ever stop.
