Hope... my advice to you would be to slow down. Most of what you are doing is based solely on your emotions. I would take a step back if I were you and just breathe. Deadlines = pressure and pressure is a MR killer at this stage. Trust me. Been there, done that. It does not work. Only give him a deadline if it is something you are sure you want to do for you.
Re: the trip to Vegas. I hate to be the bearer of bad news but I highly doubt he is going alone. Be prepared to find out there is an OW in the picture. Sorry.
My STBXH and I made lots of promises to be honest with one another. Only one of us meant it. He swore on our children's lives there was no OW. It was just more lies. They will say anything to keep from looking like the bad guy and facing the consequences of their actions. ANYTHING.
Re: going to a friends for five days... If you think that will help you detach, then definitely go. But don't go with the hope that it will bring him back to you. Zero expectations.
I feel for you Hope. I have been where you are and it is the worst feeling in the world. It will get better. I promise!!!
