Fashion, if not style too, is not just about what suits the person. Oversized stuff might be very fashionable and fun to wear and a person might well choose to wear such a trend despite it not being flattering, because the person might rather wear the oversized fashionable stuff than worry about wearing what might be considered flattering. As Angie said, sometimes, "just flattering enough" is more fun than all out flattering. And sometimes a person might not want to attempt "flattering" in the first place, and that has its own attractiveness, in that it can suggest confidence and that the person feels no need to try too hard. There are all sorts of different aims and reasons for wearing x or y. If dresses don't speak to you, don't wear them. If you nevertheless have a hankering to want to wear dresses because flattering can be nice too, then I think it is worth asking yourself whether you can incorporate what makes dresses flattering in non-dress outfits, and whether too you can find dresses that you WOULD like, as Gigi and Rabbit have suggested above.
Example: I have a theory about myself that I detest jeans, pink, and conventional outfits, yet (as I mentioned on Angie's Mom jeans thread) I recently wore a conventional (to me anyway) pale pink jeans outfit complete with sparkly heels, and I liked it. The thing that made it fun for me was precisely that the dusky pink jeans were mom jeans that are still unpopular if selling like hot cakes in Topshop etc, and that I did not hide the fact that they were Mom jeans but instead tied my (slightly darker) pink shirt at my waist, which is itself deemed a bad thing for a woman my age to do (though in practice very little skin was actually showing). Also I rolled the jeans to a cropped length. Even though I would say that there is little about that outfit that I like or would consider my style, I nevertheless enjoyed it. Sometimes it can be quite small things that can make the difference between whether a person likes an outfit or really doesn't like it. Wearing a jeans based outfit feels utterly boring and too much like what absolutely everyone wears, and it doesn't at all feel like me. For me, adding some sort of unexpected or slightly rebellious element can make all the difference.
You might dislike dresses for a particular reason that would not apply given particular dresses. How does wearing a dress make you feel? Is there some other kind of dress that would not feel like that? Example: maybe wearing dresses makes you feel powerless? Or frumpy? Or school girl like? Or as though you are trying too hard to look pretty? Then the answer might be to find a dress with an altogether different feel. Dresses vary dramatically! Or perhaps you find them physically uncomfortable? (As a dress preferrer I am always amused when people say that jeans are more comfortable, because I find the opposite.) Again, there are different styles, different fabrics, different everything that could make the difference.
Or perhaps you could find some non-dress outfits that your husband would love too? Perhaps he might enjoy seeing you in shorts if it is your legs that he enjoys about you in dresses?
