I’m at a loss...marriage advice?

A little backstory.

My husband and I have been married going on 3 years, together for almost 5.

Our relationship was rocky before marriage, as he was still quite immature, but we worked through it. Then we were great, the sex was great (almost daily), the love was THERE.

Earlier this year, things started getting rough. He lost his job and I had a miscarriage. After that, we had sex probably 10 times a month, and now we *maybe* have sex 2 times a month.

On top of this, he is constantly accusing me of cheating.

He is my first relationship. He had been cheated on in the past before we met, but there has been absolutely NO infidelity in our relationship. I couldn’t even fathom doing that to him.

I haven’t done anything to break his trust, but he’s constantly accusatory toward me.

We are both in college full time, and I work part time.

I don’t know if he’s feeling this way bc I have a job and he doesn’t?

Or if he’s trying to push me away because he’s tired of me?

He apologizes for acting this way, then a day later it starts all over again.

I love him more than anything, but this is getting exhausting...

Has anyone dealt with anything similar?

Does anyone have positive experiences with couples counseling? I doubt he would ever go with me, but I’d go by myself just to try to make things right...
