Are you saying that if your "husband refuses," you feel you cannot go yourself? Or are you just saying he won't go? (Not that this is a good thing, but husbands often refuse to go to therapy.)
Go yourself with your daughter and have a helpful, enlightening time, and let your husband see how beneficial it is, and he might change his mind. It's not like you can drag him to therapy.
Getting into arguments with him (either you or your daughter) when he is hiding behind God will go nowhere. You go, and see where you get. Sometimes one shifting pebble changes the entire plank bridge, in time.
I feel you seizureadvocate. First, I'm sorry such a young woman has had cancer and has to go through chemo! My sister in law is going through chemo and it is tearing her apart. She literally is going through H- E - double toothpicks. And emotionally, to be a young woman and all the fear that cancer can bring you and the reflection on your life, etc. Kudos to her for taking the steps of doing therapy. You know, they aren't going to fully analyze him. :>) I just went through this with my son. Both my husband and I met with the therapist. That's something that makes some people feel a little vulnerable. Maybe uncomfortable. But he can sit and listen without offering up his soul until he's ready. And that would be SUCH a gift to your daughter. Me? I think a parent that denies a teenage child's request to work with a therapist is just saying "I don't care". For real. Because it's about the message we send our kids. Denying doing something that she feels will help will never bring them closer. And she will always know dad refused.
My parents divorced when I was a freshman in college. You know what? It made me mad at them both. I'm sure I never fully got over it or all the emotions because it ripped apart my family. Their divorce made it more likely that I'd get one statistically! But you know, that's just how an older teen may look at it. If it was a good idea or not that they divorce (my parents), I have no idea. And that's not my business. But healing my own heart and repairing damaged trust was important to me after. And your hubby could play along. :>) Is he worried about being told things he doesn't want to hear?
