What do you do if you have been dating someone for 3 years but have never been to their house and is that love?

It's best to discuss this matter with the person you are seeing. It is odd you have never been to their home. If they are still living with their parents perhaps they are living with a dysfunctional family. Other than that, there is no reason this person shouldn't ask you to their home. You shouldn't have put up with it for 3 years. I don't blame you for being suspicious. It comes down to two things ... they never thought about having you over (this can happen believe it or not) or they are seeing others of the opposite sex or could quite possibly be married. Have that talk soon! Marcy
