Just: Sorry about this mess. Perhaps he is a sex addict. Please do not sleep with him again in case he has an STD if he refuses to get tested and get yourself tested. If it were me, I'd call it quits and get whatever help I needed, i.e., WIC, the local food pantry, Child Support, job training, if needed, Govt. help in paying for child care and/or family help, help from your church.
