Just got my save-the-date for october and decided to compartmentalize my feelings into this thread.
I’m probably going since we weren’t too serious, and thus remained amicable after the fallout but was wondering what other dopers’ experiences were/are/would be.
Of course. If we’re close enough that they would invite me, I’d be there with bells on and a gift in hand.
OTOH, if a friend of mine didn’t invite me just because we had dated, I would be seriously offended and would start thinking Bad Things about their fiancee. (Assuming all our other mutual friends were invited, of course.)
How serious an ex are we talking about? There were five guys at my wedding with whom I’d gone on at least one date and who were not the guy I was marrying, one invited by me (he married a good friend of mine), and four by my husband, who knew them in other contexts. One of them was a guy I dated for a couple of months, the longest I dated anyone until Mr. GilaB; we went to his wedding, too.
In a generic sense, I could see going to an ex’s wedding, assuming we’d remained friends and all that. I can’t really imagine why not.
In my specific case, I don’t think that even my ex-wife would be quite that insensitive. But if she happened to invite me, I’d politely decline.
I was invited to an ex’s wedding and would have gone, but I couldn’t afford the travel at the time.
I would be fine to go to either of my ex husbands’ theoretical weddings, especially if the kids asked me to. However, if I thought my presence would cause more discomfort for others (the bride possibly, more likely his parents an family) then I’d bow out.
A friend who is a lawyer told me about a client who purchased from him a certificate for ‘pre-paid credit toward a divorce’, and gave that as a gift at his ex’s wedding. Specifically made out in the name of her new husband!
Actually, My friend said he would let them use it for any legal services.
(In fact, that marriage did only last a few years. Don’t know if they actually used the credit, though.)
Yep, but by then he was more in the “old friend” category than the “ex” category.
Ex-husband, no - didn’t, wouldn’t, wasn’t invited. Not on speaking terms.
Ex-boyfriend, the ones I’m still in touch with - yes, went to a bachelor party for one even (they made me dress up like a guy so I didn’t stand out in the strip club).
Girlfriend from HS. We lost track of each other for years then became friends again.
When she got married in 2006 she asked me to walk her down the aisle and give her away.
I was honored to do so.
This may very well be the best idea ever! I now know what I’m getting my soon to be ex-wife when she gets married again.
I think I would go to my soon to be ex’s wedding, but only because of the kids. I want to see how they act during the ceremony and such. I highly doubt I’ll be invited.
I desperately wanted my last ex to find a nice girl and get married. Until we had a fallout recently - a couple years after breaking up, and not about our relationship - we were good friends. He would have invited me and I would have loved to go.
Everyone else, can rot in hell 
My ex-husband and his partner invited me to a similar ceremony within our religion (not legally binding) and I declined. I didn’t want our relationship - decent as it was at the time - to detract from he and his partner’s ceremony. Even a good relationship between ex-spouses will get the tongues a-waggin’, and I did not want their moment tainted by whispers of, “Can you believe WhyNot is here? I’m so glad she and Ex are on good terms! Isn’t it awesome?” No. I didn’t want it to be about me, even tangentially and in a friendly manner.
ETA: I was really, honestly glad that a bunch of our mutual friends went, though. A few of them were nervous telling me where they were going, like I was going to be upset at their “betrayal”, but I was very happy that they showed up to support them.
I didn’t go to an ex’s wedding, but mostly because it was in Syria.
Technically, I’m an American Jew. Not a good travelling situation.
If they had married over here, I’d probably have gone.

An ex and his wife came to my wedding - it was delightful.
Mr. W and I would have got to their wedding but it was in India and a touch too expensive.
My ex, who happens also to be my son’s mother, invited me to her wedding some ten years ago. I was more than happy to go. Perhaps this isn’t common, but we three are all friends.
Is that weird?
I would have, but I had a newborn baby at the time and it was hours away.
I went to the wedding of an ex-girlfriend (my first serious girlfriend; we’d dated for a year and a half). We had remained friends; when it came time for her new husband to throw her garter, she aimed him directly at me (and I did catch it).
I only have two exes and would be perfectly content if I never even saw either again. So no.
I am sure I would never be invited, but I would most certainly go, and I would cause no trouble.
I would find personal amusement for years to come if I were allowed to witness it firsthand.
