I don't know what to do, and I'm at my wits end ( question)?

Hello...discuss it with her, force the issue. Take a weekend and discuss it. Talk to a pre-marriage counselor. She may be just real uneasy in bed and literally not know what to do. If she is not enjoying it and does not want to move out, then perhaps that is why she says nothing, fear of being kicked out. Adult time, adult discussion. It has come to a head, time to pop that baby. You must talk about it. Tell her to sit and listen for 10 minutes while you outline your thoughts. Then tell her, she must talk about this. If she avoids it, that is the end of the relationship, no words speak volumes. Best of luck to both of you. All my best. Hope this helps.
