I've understood too late the mistakes I made in past relationships. Not being as warm or reassuring as I could have been. Being critical when I could have been kind. Being transactional rather than giving. Not remaining committed when times got tough.

Everyone you’ve dated in the past was once a stranger. You can get over them and it's always possible to meet someone new in the future who becomes important to you and meets your requirements. And if not, you can live single.
