New here-heartbroken and confused

[Ready2Change]

In everyone's experience, do the spouses typically attempt some sort of relationship talk after detachment?

Most of the time, people posting here believe that they can talk their spouse back. This almost always backfires (99.99998%). They have not learned to listen to understand the other person. Instead of validating what the other person is saying/feeling they switch to their POV.

When he comes to pick up the kids he always looks so sad.

During this time, you can firm up where your responsibility ends and his begins. His emotions belong to him. Yours belong to you. Best thing you can do is not reflect his emotions. You be happy, or at least project that to him. You can validate his emotions. You can empathise, but do not let his emotional state change yours. Easier said than done, but that is part of the growth that can (and should) happen during this process.

But he wants this, so what more can I possibly do?

You shine. You show him your best you. Today he may believe he wants this, but he may change his mind in the future. Give him time to process. Give yourself time to process. Let go of the outcome.
