I don't know if he will become buddy sour.
I've seen many horses kept with just one or two others that are perfectly fine, and I've seen horses kept with many others and they can be buddy sour.
I think a big part of combatting buddy sourness is to be a strong leader. The likely only feels buddy sour because he is scared of being away from his herd - a vulnerable position to be in - but if you are a strong leader the horse should be much better behaved. Like most vices, they develop with poor leadership and lack of correction. That is my opinion at least.
I do not think horses should be alone. They are herd animals and while some of them might function okay alone, I don't think its the right thing to do. Why don't you open your pasture up to another boarder? Often people just need somewhere to graze a retired horse, or something, that way you won't have to get a horse, your horse could get a friend and you might even make a little money?
If you are not okay letting people on your property, perhaps someone is willing to lease out a companion horse, one that is lame or something, but they don't want to sell? Put an add around and you might get something back.
