[insecurity] how to handle something SO said

I'll try and keep this short and to the point.

-Wife said she came way harder while using a toy much larger than myself.

-I got insecure, asked her if she really thought bigger was better

-She responded with something like "it'd be better if we made more money, and we didn't have to work so hard, but I'm here aren't I?"

-Now I'm feeling inadequate on multiple levels. Can't stop thinking she would prefer a bigger dick and a rich guy but I guess I'll do.

-I suppose i get what she was trying to say but I can't help feeling like shit.
