I have had deep feelings for a cousin for over eight years.
Why do you think that your cousin feels this way as well?
I was in an accident and he took care of me.
I understand why you would have these feelings, but it is bad to have incest relations. Maybe the feelings you have aren't love, but just a deep bond. I would try and talk to someone about it without getting involved in a relationship.
What's wrong with him?
It is only natural to have feelings for someone you find attractive, however just know that relationships among family members are not safe for reproducing. You are still free to let your cousin know how you feel I suppose!
