If by "don't slow down for any pothole" you mean that you frequently hit potholes, that could definitely be a contributing factor. Even if the impact doesn't immediately damage your spokes, it can cause them to unwind and lose tension; lose too much tension, and the spokes can slacken through parts of each wheel revolution, causing them to flex and fatigue as the wheel rolls.

To prevent breakage:
-Use good spokes.
-Occasionally make sure spoke tension is adequate, especially after major impacts.

Which spokes are breaking and how old is your wheel?

There was a window in time when non-drive rear spoke breakage was rife. The simple solution was to tighten all 32 spokes (usually) a turn. It's easier if you do all of the drive side spokes first.

Is this a department store bike? If so, the wheels are most likely under-tensioned and can be expected to fail if you do abusive things like running into pot holes. Also, on a tensioned wheel, all the spokes depend on all the other spokes. Breaking one spoke places more stress on all the others, especially the 2-3 adjacent ones in either direction. Once I pop a few spokes, I consider all the spokes in the wheel to be compromised and will have the entire wheel rebuilt rather than suffer continuing one-at-a-time spoke failures forever.

It goes without saying that hitting pot holes at speed is hard on wheels. Your weight, while not a problem in itself, exacerbates the stress on the wheels when you're abusing them like that.

FWIW, potholes are the cause for only a minority of spoke breakages, improper tension or improper build causes the majority of broken spokes. You haven't told us WHICH spokes you broke, so we can only guess.....
