First and foremost, don't marry a non-Catholic.
My advice is to try, as much as possible within the constraints of your condition, is to try and network as much as you can. Most people traditionally met within social circles, either friendship or familial. Yes there are options online nowadays but I'm sure as you've seen it can be rather difficult. Do you have trad friends? There are quite a few "mover and shaker" types who know a lot of people and can get you to invited to places to meet and make friends with other trads as well as women. Even if you find a way (friend driving, public transport etc) to meet new people (men and women) only a few times a year, you're going to have a lot more success than being locked into the same place.
It sounds very basic, but even just this can do a lot of help as well as also being able to generally meet more people which I think would also be helpful given your stated family circuмstances.
