I'm going to date my roommates high school girl
Have you talked to your roommate about this yet?
I think my roommate is happy with what I have done.
If you are of similar age there is nothing wrong with it. Your roommate even gave their blessing.
If everyone saw where I'm coming from I would be amazed.
I think that they will since even your room mate said that it was okay. Regardless, you are allowed to date whomever you like.
