How do I deal with snoring caused by weight?

I'm currently loosing weight by dieting and exercise but due to college and trying to get a part time I don't have time to loose it on a quick scale so I'm only loosing a few pounds a week.
A big issue for me is my snoring caused by my weight, I'm going to see my boyfriend in a few months and last time I was there I had a lot of snoring issues. I can't afford to get sleeping equipment.

I understand my breathing will improve as months go on but I want to try to work on this problem now. I know alot of people deal with this as snoring and heavy breathing is incredibly common for people overweight. I unfortunately cannot stay in another room, it’s incredibly embarrassing and I don’t know what to do. It’s especially hard because this isn’t something I can actually control and my boyfriend is a very light sleeper and isn’t very accommodating unfortunately, trying ear plugs but apparently that didn’t help? I’m not sure.

Any advice is helpful and appreciated,
