Our friend, a guy, is a sweetheart and we love him dearly. He is in the process of divorcing his wife (by her choice) and has been moved out since December. Lately he's been seeing this woman who has been in a live in relationship for years. When we asked if she's still with her boyfriend, our friend has said "she SAYS she's not...we're not exclusive anyway". I've seen a picture of her, and she looks like complete trouble.
Well, a minute ago he asked me in a text "Do I get a plus one?" I haven't answered yet. We're not doing a sit down meal, so the extra cost for her isn't really an issue, and we love him and don't want to offend him (though he is a passive guy) but I don't like her from what I've heard and seen and honesty I'd be embarrassed for my family to see her there...she truly looks like a cheap hooker.
I'm thinking about saying that to save money, we're only having serious couples and marrieds as dates, BUT I'm pretty sure he got an insert in his invitation saying that singles can bring dates. Obviously, he didn't notice it, but if he came across it I don't want him to get mad. What should I do?
