Not to say bothered, we learn from our past, and look forward. I always tell myself, don't ever regret of the decision made, and don't ever regret in life. Regrets made us stay in the past. My life has gone through up and down, sometimes I do look back though, but it's more like a reading a history story. We learn the mistake from the past, adjust it, fix it, and continue walking the path without making the same mistake from the past. My wife and I are at the age of 43 now, and we don't have any kids, but so what? We are Buddhist, we accepted the faith, we continue doing things that we like to do together, and life goes on ?
