Oh the joys of a relationship and dealing with children from a previous marriage .. My husband and I both had kids when we got together and him and I sat down and really discussed how we could blend the family ... We agreed that he deals with his and I deal with mine .. If he or I were gone and one of the kids was doing something harmful of course we stepped in to stop it .. but pother than that he handled his 3 boys and I handled my daughter .

I agree with the others that advised you to sit down and talk to your boyfriend about all this and set boundaries .

Good luck
