I have been divorced for a year and am the custodial parent with my ex having our son every other weekend and sometimes a night during the week since our separation in march 2009. We do not have a custody agreement but have managed to keep to this schedule without issue.
I am now dating what used to be the paramour from an affair I had during our marriage. My ex does not like this person and I am worried that my ex will not bring our son back to me after learning about my relationship.
My question to you is what I should do from a legal perspective if my son is not returned. Without an agreement already in place, what should I do?
