Good morning Peet
You should try and forget the past. If you have been hurt in the past then thinking of the past will just cause you more pain and suffering. Try and look ahead to the future. I know at times it's not easy, but rather be happy than unhappy. You have a life to live...live it the best you can. Time passes us by so quickly, especially at our age and regrets always come too late.
We all dream and it's a nice feeling. To live in a dream world is often better than reality but we all have to face life. We all get hurt and fall in our lives. Yet we fall, so we can learn how to get up and walk again.
And life often doesn't turn out the way we had hoped for. That's life :-)
Life often throws us a lemon. Be positive and overcome :-)
Have a nice day and take care.
