Let me repeat--calling the DV hotline commits you to NOTHING. You don't have to take their advice, they aren't going to call the police against your wishes. Nothing will happen unless you decide you want to take some action after talking to them and thinking it over thoroughly.
OK? This is a can't-lose situation, making that call. Yes, do it from a private place where you have time to talk for a bit. All you are doing is getting good information and advice, you aren't making any decisions YET.
Please do it--we are all very concerned about you.
