Relationship Question/Opinion

So in your opinion who should pay for couples therapy: My partner and I went through a rough patch recently where it really hurt us both because we had never gone through something as large as this and during this time he basically cheated on me with multiple women (non physical) but going on dates etc with his ex. We have decided on couples therapy to see if we can make this work and he does pay a lot of our main bills and lately we've been having some financial issues. He told me today that he thought I knew that he wasn't the one paying for therapy - I am because he doesn't have any extra money after paying bills. I completely understand this but I also don't want to pay for therapy when he's the one who cheated on me. Soooo I'm thinking of just not doing it at all.
