My personal take...
I liked the pairing initially, and thought it made sense, and looked really good, on paper. I know some readers were asking for "buildup" to the marriage but...this is comics, you really don't need a year's worth of issues (which could be anywhere from 24 hours to a month given the sliding time scale) to establish romance and a relationship...but I digress, there was precedence under Claremont (not JD's trash) when they both met in their teens and she saved him. So "Yes to the Dress!" I get wanting and having the Black Power Couple thing, Americans love their labels and imagery, and Hudlin was/is quintessentially a high-profile Black American in Entertainment and wrote them in that vein. Enh! He had some good moments and some not so good ones. McDuffie wrote them the best I think in his New F4 limited series.
I wholly agree with JWat...in that if they had put much more effort into giving them equal billing on their title and in their stories it would have worked. But they didn't give Storm that respect she had earned and deserved as a leading X-Man. Which worked against both characters in the long-run.
Now...when Hudlin (the sole driving force behind the marriage) left, Editorial clearly had no interest in continuing the marriage for...reasons. I would say racism, stupidity, incompetence, ignorance, ennui, apathy as the leading causes, and that's how we got AvX and the ultimate dissolution and annulment of the marriage. And that ending was really the very worst shyt-icing on the garbage and sewerage that was the AvX cake. And the resulting post break-up wasn't written well on both sides either...not the X-Men for Storm, not in BP for T'Challa.
It is what it is, and can't be what it ain't...they both moved on and like their fans, were okies and doing well.
Until...Coates.
Goddess alone knows I didn't read past the first "season" so I cannot objectively speak to what came after but...nobody and no one was clamouring to have them back together, romantically...not after their shyt-show of a break-up. I vehemently hated that he brought them back together. Why would editorial allow him to do this? Much like 'acclaimed' Hudlin, 'acclaimed' Coates clearly had his own reasons and misplaced racial agenda, for writing them romantically involved that had very little to do with uplifting both characters equally, so the opposite occurred. Storm got "pushed and developed" while T'Challa was sidelined, in his own damn book. Literary Karma? More like very poor writing skills.
So yes, I rejoiced when Marauders 13 came out.
Both these awesome and titular characters don't need shitty authors writing bad fan-fiction about them. That "ship" sailed, hit some bad weather, sunk, and is now lying at the very bottom of the Mariana trench, hopefully never to be exhumed ever again.
