Yes, the "never managed to orgasm without penetrative sex" line. Poor woman has been faking it for 10 years. He's insecure about his wife of 10 year's past. But it's all her fault?
There was no indication she had been cruel in telling him about her past or was withholding information from him. The issue is with him, his confidence, his insecurity, his neediness. He needs to communicate with his wife, recognise her needs are different to his, accept that she chose to marry him not her previous partners.
