I have two kids, ages 13 and 16, that are my main priority. But I have an interesting schedule with them that provides plenty of time to get to know somebody. You need to be secure enough to understand the constraints of having two schedules to work around and that kids don't get involved until the relationship is committed and healthy. I am very active in their activities and would love to meet someone with similar aged children who understands the time commitment to their children.
I work out regularly but am not where I want to be at this point. I don't mind if you have some extra weight on you, if you're a single parent and work full time it's difficult to find the time to work out. So I get that. But please be somewhat active.
My time away from kids could be any number of things. I play softball on a co-ed team in the summer, enjoy hiking, although it's been a while since I've been out, and golf, but that's been a while too. I've been busy! ..
You... are emotionally ready to be in a relationship. We have similar interests and dedication to family.
I'm sure I'll come back and edit this at some point but for now, it's a start.
