Input: First a little back story:

My husband and I first started dating 10 years ago. 

When we first me, he was in the process of divorcing his ex-wife for the 2nd time. I told him that I never wanted to be the "2nd" woman in a relationship, so I refused to date until his divorce was finalized. He came into work that day, dropped the completed divorce papers and asked if we could go out for wings and beer.

He was the first guy I ever dated (22 and **very** sheltered life), and things were going along pretty well. However, issues started happening when I went out to the west coast to help him get the last of his items from his former life out of storage. After we got the moving truck home and unpacked it, her stuff was every where....To the point that the first thing I would see when I walked through the door was a box with her framed picture on the top of it. 

He refused to get rid of any of her stuff, insisting that he was going to send it to her. After dealing with it for a year (and a year of seeing her face every day when I would come home), I'd had enough. Called the fam, packed up my stuff, and moved out.

After a few months and a bad rebound bf, we ran into each other attending a gig of a mutual friend. Sparks re-kindled, and much to my family's dismay, we got back together. When we got back together, he made some serious promises, such as minimizing contact with his ex unless absolutely needed (they ran a business together and had unresolved tax issues from the dissolution of the business). Fast forward a few years and we're married and moving out to the west coast, while she's remarried with kids on the east coast.

Over the years, he's kept minimal contact, but over the last year they've become full blown best friends again. FB posts, chats, emails back and forth, and while I've tolerated it, we've been fighting over it more and more. To the point that during one argument I told him he broke his promise to me when we got back together. 

Now, he's significantly older than me and is turning 50 this year. It's going to be a huge birthday bash for him, but he wants to invite his ex-wife. The one who I really do not ever want to meet face to face, and have told him so on multiple occasions. His reply is that it is his birthday and even though he expects me to organize it, he wants her to attend. 

AITA for absolutely refusing to invite her and giving an ultimatum that if he wants her there then I will go visit my family instead?
