Should I take a divorce at 38

I am planning to take a divorce at 38 and search for another partner. I plan to have 2 kids. Am I too old for this?

Do u think its wise for me to go for a divorce so late in life and try for 2nd marriage?

I am worried that even if I do get married by 39 and have two kids by 41 I will be too old by the time they are in college and worry I may be too old to get them married or may not even be alive to settle them down in marriage.
