Sadly, many people are using their children as pawns and scapegoats because of the emotional ties, bonds, and feelings they still have for their exes. You're wrong!!!! All it does is cause more issues for everyone to include the children. There should be clear boundaries that exes and children must understand and not be allowed to cross. You can't give a child everything, there has to be boundaries. You can't do everything a child ask of you, because sometimes you need to say no, because what they ask isn't feasible of you being a person with another significant other. You can't make up for lost times and there shouldn't be a situation where your new significant other feels they're not wanted or accepted, because your child want it to be just their mom and dad. You have to be able explain this to your child/ren. You have to know how to have a healthy balance and do not cross the boundaries you've set or let anyone else cross them, to include your child. People, to include your child, treat you how you have taught them to treat you. Always be there for your child, but in a mature and healthy way, not through emotional ties and lingering feelings for their mom or dad. Be that parent who set good and solid boundaries for all involved. When children know your weak concerning them, children can sometimes be manipulative, especially if coerced by the other parent or if it's the child's own doing. You shouldn't have an obligation to the other parent but to the child. There should be clear boundaries set. Never give anyone empty promises, just be honest!
