So I'm dating a guy that has a 12 year old son. We've been dating for almost a year now and it's definitely been interesting and different. Him and his son's mom have a good relationship for their son (they haven't been together for like 8 years). I have never dated a man with a son, so it's been really different for me. I'm not really sure where the line is....what I can do, what I can't do. Luckily, his son is nice and behaved, so I don't have to worry about discipline or anything, but what's my role? Where do I stand?
