Just describing the situation in which Linda (Rose Byrne) finds herself in Mary Bronstein's descent-into-hell motherhood drama If I Had Legs I'd Kick You is enough to provoke the state of heightened anxiety that the movie seeks to create in its audience.

Awful? No. If you're worrying about betraying your cousin, she can't (and doesn't seem to want to) lay claim to every former paramour. But there are a lot of intertwined relationships here, so I would tread more carefully than if the handyman were just a casual acquaintance.
