<human>: Give me the gist of the text in a nutshell

Here's the deal: (obvious throwaway, as my bf is an avid redditor- but he's at work and hopefully won't see this)

-we met 1.5 years ago while I was still married (it was ending anyway)

-instant attraction and we have been together ever since

-I am in the process of getting divorced but for financial reasons need to wait to file till after a big financial deal goes through in his (soon to be ex's) company which has delayed things a bit.

-under the circumstances of how we met we have some trust issues but nothing that hasn't been worked through

-Tuesday would have been my 8th wedding anniversary and I was feeling strange about the whole thing... Made plans with a friends to have drinks and it should be known my bf and friend DO NOT get along. When I showed up, so did my ex. He had asked where I was through my friend and she told him.

- once the ex was there we had drinks and it was about a 5hour slice of my old life. No fighting, just fun conversation and old times. Nothing in appropriate. When I went home I told the ex it wasn't cool that he did that but i did understand why (bc of the day) and he went to his hotel I went home. 

-talked to my bf the next morning and hadn't really processed the night and things did not come out the right way and he assumed I was lying bc things didn't add up, i emotionally cheated on him etc.. I really was just tired and didn't know how to tell him what happened. So I fucked up. (I'm not the best at communicating when it comes to shit like this)

-he told me we should take a break until I figure out "what I want" but I know what I want and it's him. I love him so much and am willing to do anything to prove to him that a.)nothing happened b.) he can trust me 

So reddit- any suggestions on what to do/not to do tonight?
<bot>: I didn't break the news to my boyfriend about an innocent evening with my ex the right way and he's going to breakup with me now. I fucked up and need advice about what to do when I see him tonight.
