<human>: Can you condense the text into three sentences or less?

So I live with my grandparents currently until I graduate and move to Philly. My bf drives every other weekend to see me. My grandparents always give him his own room since they are both extreme on the catholic beliefs. Of course us wanting to be with each other means us sneaking around and sleeping in the same bed but leaving before anyone else can see. Well this morning after I leave for work I realize I never closed my bedroom door last night, so my grandfather saw it this morning. I know this because my bf texts me freaking out about my grandfather confronted him in the kitchen saying how he abides by the catholic faith and does not want us shacking up together under his roof or he can find another place to stay. I am simply horrified and so is he. I am not sure how to confront this without making it seem like a huge deal, or disrespecting them more than already has been done. I just got home and so far they have not said a work and I don't think my grandmother knows. Any suggestions on what I should do or say? Not sure if I should bring anything up unless they bring it up first.
<bot>: bf visits for a week at my grandparents. Grandfather confronts bf about us shacking up with each other.
