Hi, PinkPearl, I think it was only natural, as you say, given the man's line of work, that you would reach out to him. You understandably needed someone to talk to.
Please don't be hard on yourself for sharing. You might feel a bit embarrassed or anxious about it right now, but that will pass. He will get back to concentrating on coaching hockey and lacrosse, and you can go back to being a hockey/lacrosse mom.
That said, please do find someone to talk to. I recommend a therapist. I am sad to hear about your being in a abusive situation--and it needs to stop. A therapist can also give you some support. Okay?
