Losing health insurance

Long story short, I’m losing health coverage from my job as I’m going into my next one. The next healthcare that my new employer has is a health care sharing ministry. I’m absolutely not all about that, and have seen a lot of reddit users not recommend it as well.

So I’ve enrolled in the healthcare.gov marketplace coverage and had a few questions before looking at anything on there. (I live in Ohio)

-It asks about “household income”. I live with my boyfriend, not married. Would I only enter my income or both of ours? (I am not eligible for Medicaid)

-I have used Anthem in the past and liked it. I looked at their individual plans so far and would choose a silver one. Since I also am available to have the marketplace coverage, I qualify for tax credits. Is it worth it to pick a marketplace plan and take the credit? If so, how much credit would I use to lower my premium; is it better to leave some leftover?

I have a second job that is based on commissions in a way, and it will change every year. I know I have to change the amount of income based on that.

I am very interested in knowing everyone’s opinion on the gov marketplace plans because I have only used employee healthcare up to this point.
