Just looking for some creative assistance on wordplay here. I am currently baiting a scammer who says there is a fund waiting for me in the Cote D’Ivorce - which place I assume is the opposite of Gretna Green
Epole, presumably.
I think of eloping as running off to get married. Running off to get divorced? Isn’t that a Nevada Divorce?
Shotgun wedding.
Opposite in what why? “Jilt” is suitable if one of the party runs off to avoid a marriage.
Delope
Antilope? 
The opposite of elope would be to endlessly delay a marriage, wouldn’t it? Like a permanent engagement.
Unlope
Good luck with the baiting. I used to do it quite a bit.
I need to get back into it.
Isn’t elope running off to get married? Wouldn’t the antonym be not running off to get married? So . . . wedding? Marriage?
Although I like antilope suggested earlier.
Elopement is still a type of marriage or wedding, though. Couples who elope to Vegas can still have a wedding ceremony, and will still have a marriage in place.
The opposite of elope is to essentially have a more traditional-style wedding and ceremony with your family and friends, in varying amounts. So I feel the most concise way of putting it is a ‘traditional’ wedding. Obviously what’s traditional and what isn’t differs between groups of people, but I’d say an elopement isn’t ‘traditional’ in most groups, if any.
Edit: Although I’m with you - antilope is pretty awesome
Or both not running off and not getting married, so the concept of a perpetual engagement, as suggested by Alessan, is what first came to mind to me.
First time I laughed in a few days. Thank you.
Bridezilla?
Since nowadays most elopements are to avoid the over-the-top wedding stuff
One might say they have been havisham’d.
I guess by the opposite of elope, I meant where people would romantically run away to in order to get divorced. Not that it would happen all that often, of course.
I like Antilope, I will use that!
Enjoying the discussion!
This is EXACTLY my first thought as well.
If elope means running off to get married, then the anti- would be not being able to run off.
i.e. cantalope
Antilope, cantalope, both are ABSOLUTELY BRILLIANT!
Unlope is pretty damn good, too.
