I've seen no indication she is looking for a BF. When she first arrived it looked as though she may have had one. Still not sure about that. The lack of interest in what she did last night is more likely because most don't care what the girls get up to when they are out.
Depends on what happens. Look instead of making a comment the would just cause a stir I'll just say I'm not enjoying the conversation in here at the moment. So I'm doing what normal people would do. I'll look in on the girls some and in the mean time do something else.
