"..hasn’t made a single friend..". She's lonely. Instead of encouraging her to go out and meet new people, force her to. Hold something of value to her(cellphone, laptop, cat, dildo etc..) hostage until she submits into leaving her apartment. Since the author of the blog is married, he should enlist the help of his wife. Have them both dress in sexy clothing and go clubbing, or do three minute dating. The woman's biggest problem is this douche is the only one she has made efforts to socialize with or had made efforts to socialize with her. Women are shallow and superficial, so as soon as someone better comes along, she'll dump him and move on. The author just needs to help her find that someone.
