The weapons breaking does get way better later in the game as you get more weapon slots and more durable weapons. It's definitely at its worst right at the start, which is unfortunate.

However I will note, playstyle has a lot to do with weapons. If you are swinging wildly, your shit will break.
Being more careful with openings in attacks, going for high-damage combos instead of a million chip damage hits against their shields, and most importantly using stealth strikes which seemingly do not take off any durability is really important.
