Aaron Marino of alpha m. gives advice about how to handle a relationship where you feel that her career and appearance exceed yours. Do not screw-up a really good thing due to insecurities.
The fact is that you ARE dating her, and she likes you. This is a great thing and yours to lose. She likes you for reasons, so don’t do anything that sabotages that. Don’t keep searching for reassurances that she likes you or that you are good enough.
Take this girl and treat her unbelievably great. Be the best you for this girl person. You don’t have to be a macho machine to win her heart, as it sounds like you already won her heart. Simply be there for her.
