Dear T.,
This is so serious that I don't dare tell you anything to do, EXCEPT you absolutely must go for legal help yourself. Does the Navy have an office that guides families? You must keep on this until you feel safe for yourself and your baby.
Do not let any of the 'sorry' and excuses even influence you. I know, your husband is a love, but your daughter's life and future is right now and she cannot protect herself. You are the one that has to be strong, not mean, but strong.
Do not worry about damaging his reputation or doing anything that will harm him, he can take care of himself - or someone else can take care of him - you need to take care of yourself for your daughter's sake. You don't want her to be one of those runaway - throwaway kids when she is a teen. Keep her safe and keep yourself sane.
You can get help, just reach out until you get it.
Sincerely, C. N.
