Not exactly “invite”…
My first wedding (since divorced), got crashed by an ex of mine. She was suffering from mental illness and had been stalking me for years.
Two of my best friends were assigned to sit on either side of her during the ceremony, and to be ready to quietly restrain her, incase she decided to disprupt things. She didn’t do that, but had also booked a suite at the same hotel we had honeymoon in. Apparently she had tried to book the room next to ours…
She still occaisionally shows up, at my work place, or other places. Funny thing is, she dumped me, and really dooesn’t like me that much.
We had a few of these sort of things at our wedding.
Prior to meeting my wife, I had a year long fling with an older woman (me 23 and her 38 and recently divorced) who wanted me strictly for sex. We were never in love. After a year together, she had a male friend her same age that she wanted to start dating and she was very honest with me about that, so we broke up but actually stayed friends. I invited her to my wedding two years later and even told her to bring the new guy. She ultimately came alone and I have no idea if they were still dating at the time.
In addition to that there were two other ‘crushes’ at our wedding. My wife had a long time crush on one my groomsmen in college, but nothing ever came of it because he was never interested. Likewise, one of the female guests at the wedding was a former co-worker who I also had a major thing for, but who was never interested in me. I’m not sure these qualify as “exes” per se, but are along those same lines. I was aware of her quasi-relationship with my groomsman, and she aware of my thing for my old co-worker, so there were no secrets and everyone got along great at the wedding. The only asshole guests were actual family members, but even they kept in under wraps for our wedding.
I didn’t invite any exes to my own wedding, but I was invited to the wedding of a serious boyfriend whom I lived with for seven years. In fact, my husband DJ’d the wedding.
My ex-husband is still one of my closest friends and I consider him family. He not only came to my wedding but he was in the family photo shoot and at the reception he “passed the torch”* to my new husband, saying “she’s all yours now.” There was no weirdness or drama.
