My girlfriend’s children are rude and get whatever they want from her. They are thankless and demanding. This is a woman I love and I am trying hard to help her with being a single mom. I was raised with strong discipline and my dad was never afraid to give us a good hiding. I think I should step in and give her children their limits. She says I better not touch them. This makes no sense. She can’t handle them and won’t let me do it. This is going to be what causes us to break up. Please help.I’d suggest you do not, under any circumstances, resort to any form of physical punishment with the children. You are correct: this issue will probably result in the breakup of your relationship. Interfering in pre-existing relationships will almost always get a person in trouble. I’d suggest that you try to accept that your girlfriend will inevitably side with her children (over siding with you) even if the children are “demanding and thankless.” While we’d all prefer to live in a world where children were less-demanding and filled with appropriate gratitude, these are not values that you, the outsider, will be able to impart.
