Here I see there are two insecurities: 

- Her insecurity invokes your insecurity
- Your insecurity invokes her insecurity

That's the intrication, the convolution, the complication that any couple has to deal with before they can really "two becomes one".

This depends on the specification of the situation, the unique of the individuals, that both of you have to figure out how to solve this. This takes time, this is hard. But once you reach that point, you can share with each other the deepest dreams, the deepest desires both of you have.

Don't worry. As long as you can make sure that you will love her no matter what, then it will be fine.
