TS: men earning less than their girlfriends VS their girlfriends getting frustrated by it

not sure how to solve this beyond the obvious solutions like 'get a new job', which isnt as easy as it sounds, but im getting very self conscious about it (even though i dont sponge off her) and am starting to think that shes on the look out for someone with more cash. i may just be getting paranoid though but have always tried not to bring it up in conversation very much as money is not something i like discussing n relationships, and i dont want to bring it to attention, i.e remind her of this more often than necessary.
