I'd say give her a big slap, and then think about joining a running club

If you're really feeling like you're not ready for that, then carry on as your are for a while... training alone I find gives you time to clear your head of daily stresses etc, and also means you can focus on the goal of your run a lot better
Certainly don't give up, it's not the end of the world... she's probably holding you back anyway
