In other news.. I just found out one of my closest friends is having an affair

I already suspected it and suspicions were confirmed. She's always been really supportive of me and I'm having a difficult time with this. She's asked me not to tell my husband (husband and I know her boyfriend well). I hate that there's something I can't tell my husband. I'm not going to because I want to respect this wish of hers.. but I think I do want to tell her that I don't want to socialize with them as a couple while this is going on.. ugh.
She always mentions how great it is what I'm doing, with the honesty and openness, but she can't do this herself.. I don't want to judge her but feel so bad for her boyfriend. Ugh, again.
