First, questions should be:
1. Is there a possibility I get the visa in absence of a legitimate relationship? as she can't be predicted.
4. My new girlfriend who is more matured in reasoning really wants to date a married man who she has never met (?) but who loves her very much, even though divorcing his current wife isn't his decision.
I'm sorry, it seems like phone records are the least of your worries at this point. You don't have to be in the US to divorce your wife. Or to date someone else apparently.
