I don’t think you are wrong for feeling the way you do, but as long as you are living with them, they can set rules for their house. Sure, it sounds like they are over protective and a bit naive with their thoughts about you having a relationship, but until you are ready to move out, you’ll have to deal with their rules. You could try talking to them about it and try to meet in the middle on the things that are making you feel smothered. It may or may not help, but you won’t know until you try.
