Dear Masculine Bae with a Mental Obstacle,
You have a Bae who loves you, so open up to your Bae and let your Bae help you. Have compassion for your Bae who is worried sick about you, and ease into talking about your issues with your Bae. Your Bae will never know or be able to help until you start talking. Practice action-therapy vs. numb-therapy, meaning, take baby steps to confront your problems.
I dated an extremely masculine Bae one time who ignored EVERYONE when he was in a funk and just numbed out on who knows what.
