whenever I'm feeling down about things, especially my DH, I retreat into dreaming about a past relationship. this relationship is a long way in the past - I have been with DH 17 years - but I can't seem to stop this negative thought pattern. I think it's avoidance but just want to stop it as it really doesn't help and makes me feel a bit stuck in regret about the past. it also makes me question whether I can really love DH. obviously after 17 years and two kids there are no rose tinted specs about this relationship! How do I stop this and focus on now!
