Strange as it might sound then feeling sad is probably a positive thing…
It indicates you realize what you risked and the seriousness of your actions.
I want to make a suggestion:
Reclaim your anniversary!
Make it your special day.
Go plan something special and unique for you and your wife. Nothing to do with the kids, no other people involved. Only you two. Preferably something more unique and special than the annual Red Lobster dinner.
It really doesn’t have to be expensive, complex or hard to implement. The main thing is to do something together and to show her you took time to think, plan and implement.
Some suggestions:
Go to a spa. Get a massage side by side, sauna, Jacuzzi… and then a light lunch/dinner.
Go to the theatre. If possible take an early show and then dinner.
Go to that special French restaurant that you need to book way in advance.
Broke? Well – make some sandwiches, buy some chocolates, chill a bottle of bubbly, find a blanket and then you two have a picnic at some scenic site.
One thing I did for my wife (but I do admit it took a super-human effort….) was to go shoe shopping with her! Yep. I allowed her to drag me into 5-6 shoe shops and helped her try on 100 pairs. Then walk back and forth between two shops to decide on the final couple of pairs that she was thinking of buying. Never a word of complaint, always showing interest… My wife has mentioned that day as having been a watershed in rebuilding our relationship.
(Note – There was no infidelity in this marriage. I was a BS in a former relationship. But we had to rekindle our love after an ILYBNILWY moment.)
