Support needed: My spouse is struggling to understand

This is hard to write, but I need some advice.

My spouse never served, and lately there's been a disconnect. They don't understand why certain things trigger me, why I need my routines, why I sometimes need to be alone.

I love them, and they love me. But there's this gap that's hard to bridge.

Looking for advice:

• How do you explain military experiences to someone who hasn't lived it?
• Any resources for spouses to understand veteran issues?
• Tips for couples working through this together?
• How do you balance being open vs. protecting them from the hard stuff?

I know other military couples have navigated this. What worked for you?
