Same if he calls you to vent. If you're up for it and want to listen, do it. If you don't, let it go to VM and he can be in a bad mood when he gets to OW's house. You get to decide exactly how much of the friend Wayfarer he gets right now, and you are under no obligation to be his friend if you don't feel good about it.
may's advice here immediately made me think of your comment on wooba's thread, wayfarer. If you're not always available to vent to, maybe he won't be able to walk into OW's house in complete fantasy mode, having left all his "real-world" worries with you. Too bad! But, yes, I agree that you should decide based on what you're up for. You can control how you respond when he's hoping to vent or come at you with more small talk.
Rage room and mani/pedis! I love it! It's like you're hitting the full spectrum of self-care/GAL there.
