Never did understand the phrase "no regrets"; That's a person who is incapable of learning or a liar. Everyone makes mistakes of one stripe or another and if you think you haven't, you just did.
Made mistakes - learned from them. HAPPY I DID SO means "no regrets"
I was married 1999-2006. I will not, do not and can't stand that woman to this day. Doesn't mean I "regret" it because I don't. I learned a ton and got my son out of the deal. Why would I regret that - even though it was a crap situation/6 years?
Understand the difference - regret means I wish it never happened vs realizing that it happening ended up good in the long run. Either in lessons learned or in getting me/you to a better place.
