Re-opening the wound from old romance. Is that a good idea at 58? Just reunited with old beau at reunion.

Revisiting old love. One of the usually nice things that happens as we age is that we become more mature, settled, tolerant, and relaxed in ourselves. All these factors give relationship building a much better chance. However, character itself does not tend to change much. If there was something about his personality that really annoyed or upset you (other than immaturity), there's a good chance it is still there.
