Your friends mean well. They want you to be happy. That being said, they're also probably not relationship experts, no matter how many times they've watched The Notebook. Sometimes advice given with the best of intentions is still advice from your friends that you need to ignore. But then again, sometimes they're dead on. They know you better than anyone, and they can be objective about a situation when you're too fogged by feels and boxed wine to see the forest for the trees. So what do you do?
When I worked with couples as a Domestic Violence Victim Advocate and Planned Parenthood Certified Responsible Sexuality Educator, I had to undo a lot of "well my friends said..."
