Your entry is always at the discretion of CBP. Nobody here can tell you whether you will or will not be admitted.
You seem to have some red flags - lack of employment evidence, recent extended travel and a US fiance.
One upon a time, a while back, I presented at the border for an 80 day ESTA trip with evidence of funds and a letter from my employer and other ties to home (mortgage, car) and a return ticket. The officer told me she was *this* close to not letting me in, and wasn’t remotely interested in looking at any of the evidence I had. So I was let in, but it was a close call. It really is just down to their own tolerance and feelings in the moment.
Your question makes it clear you are aware of the risks anyway, so that’s a good start. I’m sure you’ll make the best decision for yourself. Good luck!
