I hurt my gf sleep walking and now shes scared of me
Wow, Do you really sleep walk?
I get sleepwalking from my father's side of the family
You should look into ways to solve this issue so that you don't hurt the people you care about. Have you thought about talking to a doctor about ways to stop the sleep walking?
No I would rather not talk to a doctor.
They might have medications what can stop you or maybe you could try sleeping in different bedrooms.
