<human>: Could you distill the essence of the text into 1-3 sentences?

Hi. So I work as an assistant at a small (2 person) film company. I got this job via a cold email I sent out to lots of companies open to really whatever was offered to me in the name of experience.

I like the people I work with although my boss's management style has been really challenging to deal with. He will ask me to write up an email to a client and then spend 10 minutes re-writing it (while also praising what I've already written). We share a list of tasks that need to be completed -- I can't do/start a single task without getting more information from him. I've asked for particulars in many instances, often hearing, "I haven't decided, let's do it later" or "Actually, I'll handle that...". 

I do have tasks that I've been responsible for ongoing (I've been there 5 months now) and I make sure to keep myself on task and manage my time as best I can. Some weeks I'm there close to full-time hours and other weeks my boss is out traveling so I check on packages/the office or just take the week off.

Last Monday he texted me (after I had a short day the friday before) that the office was a mess so I shouldn't come in and he'd just need me to work remotely last week. I completed a couple of tasks he asked me to. I followed up about a few tasks I would have totally completed had I been given more information.

So, now I'm waiting for him to tell me when he needs me again. I am not an actual employee so I get paid as an independent contractor (though I'll file self-employed). I'm basically just paid whenever he has the money to pay me. Only once or twice have I spoken up about any dissatisfaction only to be told he just needs me to "handle it". I've observed his interactions with other colleagues and companies and it scares the crap out of me. 

I did two informational interviews at two other companies and I'm considering emailing him (along with my latest invoice which he's asked for) that I won't be available after March 1st...any uh, advice? First time posting in this sub...
<bot>: working at a tiny company for a boss who is tough to work for and now doesn't have the time to manage me...should I stay?
