I was about that age (14) when my parents separated. It's a tough age to meet a OM. My dad had an OW and was ALWAYS trying to get us to do stuff with them (camping, horseback riding, etc...). I HATED it. I did those things, but shot daggers at her the whole time. My older sister decided not to be included in anything with OW. Looking back, I really wish I had been wise enough to stay home. I didn't need to be exposed to my dad and an OW. What would have been great would have been spending time doing quality things with my dad ALONE. Your wife would be wise to do those things with the kids. They need both parents.
