First thing, are you in a fault state? If one option is to file for D citing adultery then print off some of that FB info. Any proof is good to keep on hand. I still have copies of emails tucked away just in case I need them someday.
After that, stop looking! If you can't, unfriend H
I totally understand the feeling of humiliation. The first thing I did when I got the confirmation was to call my friend M who works with BF and asked if everyone in the office knew and was laughing about me and/or pitying me. I didn't want to socialize with any coworkers for a long time because of that. But thing to remember is that you are not the one who is having an affair. H and OW should be ashamed because they are the ones in the wrong.
Meeting with the L tomorrow will make you feel better. If nothing else, knowledge is power and knowing your options is empowering.
If you don't like the ups and downs of the roller coaster, get off. Make the choice to live your best life without him right now, don't put it on hold waiting for him to come around.
Yes, embrace the suck. I know you can do it.!
If you love somebody, set them free. http://tinyurl.com/2empx2g
