 I want to know the truth. I want the DNA testing. How do I break it to them? My sister's getting married in October, and I don't want to overshadow her wedding. I'm in college trying to focus on my work. I'm extremely hurt and confused. Kathleen. Kathleen, get the DNA testing. Never be afraid of the truth. Never be afraid of facts. The timing is unfortunate with your sister, but even though you say you love her, she doesn't call you on your birthday, and it doesn't sound like she told you the truth.
