I agree with the general consensus here. At least try it. I am myself a big western fan and don't find it boring as there are so many different things to do with it. But on the other hand to keep yourself from getting bored, I suggest you try to vary your western "routine" as much as possible and try everything you can/want to with it. Trail rides are my favorite. And trail class, barrels, pole bending, etc etc etc. But I do think to be a more well rounded rider you could and probably should take some english lessons for a while, especially since you are obviously interested in it and have the opportunity.
