Your first issue is that the walkthrough is for the version of ep 2 without Bardie. So just ignore it. Follow your in game event list. Bardie and Betty are kind of dependent on each other early in ep2. Generally to level up Bardie, Monica needs to first show him her panties when cleaning the house then clean without panties. Do the events related to Betty if you have run out of things to do with Bardie. That will open up more Bardie events. Have you gone to the gym to carry Betty's bags?
Let me just reiterate. Don't follow the walkthrough for ep2 if you are playing the version with Bardie. Use the in game Event list.
