black8 - I also have boxes and boxes of cards from W, kids, and I from our lives together.

Put all the cards back in the box and place it in storage for a while. Looking over stuff like cards and pictures keeps you attached, and you are correct it will cause you pain. Put them away and forget about them for a while. I would not throw them out, atleast not yet. You many just want them in the future.

You don’t have to make any decisions about what to keep or throw out right now. You will have time later.

Sending the child support in a card. That is most manipulative, and not a good idea. It would scream pursuit and probably send her running even faster. I know how you feel, and how you want to try something to wake her up. It just doesn’t work that way.

Give her space and time to work through what she needs to work through.

Focus on you and kids, and work on detachment. Once you get it, the rollercoaster will be over or a lot less and you will feel much better.

Keep posting and asking questions.

You are doing well black8. Stay strong over your anniversary, it will pass, you will be better.

Feelings are fleeting.
Be better, not bitter.
Love the person, forgive the sin.
