This seems to be some type of present tense, but guides to verb tense only give the following two options: present progressive tense and present perfect tense. Present progressive tense uses a present participle "I am breaking", and present perfect tense uses the past participle, but with "have", e.g., "I have broken".
Wikipedia tells me that "I am broken" is a stative passive sentence construct. That is, "broken" is an ordinary adjective derived from a past participle and denotes a state. But it seems to me that "breaking" and "broken" can both be states that serve the same function in English. For instance, the state of breaking can be used to describe something (at least in engineering) that is progressively deteriorating. "The car's suspension is breaking" could be used when the car still drives but it is a poor ride.
So why is it that "breaking" is treated a participle that forms a new verb tense and "broken" is a participle that just functions as an adjective? This distinction seems like convention rather than logic.
Any help is appreciated.
