Toxic Family and Failing Relationship

That’s not true. You’re not toxic! No one is toxic. We only have more problems to form relationships than other people

Without the details, I can't form an opinion. Sometimes people blame everything on someone else because they don't have the emotional capacity to admit when they're wrong. If that's them, you probably have noticed it before. If you haven't, then the description likely fits you instead, and the truth hurts.
