I do know when me XW first moved out she was all about dating and partying when she didn't have the kids. I will say that 2 years later it appears that has died down and she no longer gives me that impression. Her life has appeared to have stabilized.
The Dr. has her son full time and outside of Cub Scouts he is not involved with anything else. The Dad lives over an hour away so she doesn't have the time to enroll him in anything else. His schedule is her schedule so he goes to bed at 7:30 pm wakes up every morning at 6 am and she has him to school by 7:15 am every morning so she can get herself to her office by 7:30 am. The good thing about the Dr. is that his school, her office, and her home are all within a 3 miles radius of each other so she literally doesn't have to leave that bubble. The downside is that she doesn't get a chance very much to leave that bubble, she misses out on a lot of networking events, and always has to find a sitter to watch her son if she wants to go out or whatever.
My issue is that I don't approach sports from the point of view of just having fun and enjoying it. I approach it from developing you skills, winning, and working hard to be the best you can be. Then once you start to improve begin playing harder competition so you can continue to challenge yourself.
