a place where everything is not okay

I found a sexual partner she is as they say "way out of my league" and if you read my previous posts you will realise how hard it was

She is a switch too like me when I am the dom everything is ok but when she is the dom and I am the sub she goes over my limits but it's not her fault because I never told her... 

I'm just afraid that if I said anything she will Leave me because that's the way she like it and she really makes me happy 

I really dont know what to do we are meeting tomorrow what should I do so she won't leave me?
