I think that depends of your ages. I look a the stage of each person’s life. I had my children later than most people so I related to younger women who had children around the same age as me.
I also think that regardless of the age is to go for it for there are no guarantees on whether or not it will work or not regardless of the age.
For me my criteria for a partner is whether she is self aware and kind. The self awareness tells me that she owns her baggage and take responsibility for her part of the relationship. This makes communicating and dealing with differences a lot easier.
