I will do anything to protect my children and put them in life and have given up a lot to ensure that they know that ~ if you refuse to do that then please don't ever mistake yourself as a "parent". you are nothing more than sperm donor.
Don't let someone who did you wrong make you think there's something wrong with you. Don't devalue yourself because they didn't value you. Know your worth. If you have a couple solid people in your life you can trust, you're golden.
