If you have children, it really doesn’t matter how old they are, if you are the other side of their maternal/paternal relationship, you will come up against tricky verbal walls.
Those walls can be incredibly hard to overcome and you may find yourself questioning your methods in dealing with situations that arise in everyday life.
Simple conflicts can find emotions inflated when you assume the role of absent parent.
Your choices are to pass responsibility off for fractious events for the child’s blood parent to deal with, or to deal with situations as you see fair and fit.
Whether you are in a long-term stable or a new found relationship, the best tack to take is the latter with the addition of simple honest dialogue; it’s a hard one, but you can do it.
