Do you think my wife would be offended if I sent her a link about OCD that has a test in it?
Maybe, do you think she has OCD?
I think she does. She's very forgetful. I don't want to offend her but I want her to read the information and take the test.
Always do your best to keep the doors of communication open and offer feedback to your spouse on your concerns for her. Listen if your spouse wants to talk, or just spend quiet time together.
She needs to take the OCD test so we know what we're dealing with. I may have to trick her to get her to take it.
Your wife wouldn't appreciate being tricked into doing something she doesn't want to do. Try to talk with her and encourage her to talk to her doctor about OCD. The doctor could diagnose her much better than an online test could.
