I know this is an old post, but it's a comment so common I hear it in real life too. This is what I don't understand. More than half of your adult life was spent in a marriage that ultimately failed. I assume that the quality of the marriage poor if it led to divorce, and you mentioned the divorce itself was miserable. It always floors me how common it is for a man to endure something like this, and how their main goal after getting out is to start the cycle all over again with another woman. Why? How many married men are actually happy? 10%? 15%?
My suggestion is focus on yourself. Put your free time towards things that you value and bring you happiness. Instead of getting hooked up with another middle-aged female that undoubtedly has kids you'd need to raise and the hope that she'll let you have a room in your own house (i.e. the mancave) just skip the woman and focus on friends, family, interests, and hobbies. If a woman does come along make sure she compliments your life instead of dominates your life.
As the saying goes: No wife, No strife.
If you're having confidence problems the last thing you should do is pursue a woman who will exploit that weakness.
