Fiancé doesn’t help financially when I’m in need

So during covid I lost my job. & I’ve been struggling to get back on my feet ever since then. I settled for a job that doesn’t pay the same just to try to keep up with my bills. We split the mortgage. Since I get paid my Medicaid I don’t get sick leave much less vacation paid days. This last month I struggled to pay my side of the mortgage. I gave him 85% of it. & told him that I would pay him the rest when I got paid again. My paycheck went to mortgage, other bills and a couple gifts. He knew I didn’t have any money left after that. I sold my bed and my bed set and he took the money that I owed him out of that. Little did he know that he left me without even having money for gas. We used to travel a lot when I had my other job. Now we’re supposed to go on a huge trip to a country in Africa in the next couple of months and I don’t have a single dollar to spare right now… I was just venting to him about how I don’t understand how I’m supposed to do this trip as he said that I’ll need at least $3,000 for the trip for my half. All he said is it’ll get better… & then reminded me that I need to pay him for our car insurance soon… I feel so sad and idk how I’m supposed to feel right now. I just feel so stuck… this is also after he asked me to help him pay for the electric bill… which he usually pays. But that’s only because it’s usually really low. He doesn’t let me turn on the heat in our home without a fight.. I had friends over this weekend so I turned it on. So he asked me to help pay since it’ll be higher. He knows I’ve been drowning since I lost my job and it hurts that he doesn’t try to at least truly comfort me. He has a whole career and just got a huge promotion. He’s definitely not hurting for money. I don’t know how I should feel or what I should do. I just feel so alone.

Add on: When we’ve had discussions about how he makes me feel. He talks about the gifts that he’s given me. They’re not consistent. They’re gifts for birthday and Christmas. But talks about how he spends money on me there. & several of years ago he paid for me to get my nose done, because I had broken it and it made me insecure. He paid for it as a bday gift.. since he’s done these things I feel bad asking him for help and I just wish he would see it when I’m crying frustrated over not knowing what to do with myself. I feel like a failure not being able to financially do what I want and need. Especially because I’ve been financially independent since I was 16.

Another update: he’s definitely not struggling financially. He made 6 figures before his big promotion… & literally made $500,000 in three months investing in crypto. I’ve seen the proof… my very successful brother has gotten him there with crypto…

Most of you are telling me to let go… how do I even begin to do that? I feel so embarrassed in every aspect especially telling my family.
