Can yoy say there is remorse if he will do it again given the chance to go back to that time

My husband confessed to cheating about 2 years ago. The sexual affair lasted for 3 months. He said he knew that he would end it before it even started. He claims that he resorted to an affair because we rarely have sex and he feels ignored. Its true that we dont have sex often and i wasnt able to give him enough attention primarily because im working for our family. He's a house husband. He's actually the one who initiated the idea of staying at home to work on the renovation of our house and take care of our son with special needs. We agreed on this arrangement about 6 months before the affair started.

Now he confessed and said he's sorry and wanted to rebuild our marriage. He's been brutally honest about the details of the affair and I can really see he's making an effort to serve me and take care of our son.

However, when i asked him if he truly regrets what he did, this is what he said to me:

"When I look back at the sex, I still see it as a nice therapeutic experience. In a way, it has helped me through some dark times. Although it is also the cause of dark times. I regret hurting you. But when it try to think if I didnt do it, i cannot say that everything is ok. If i didnt do it, i will still be curious. I want to be honest, id still do it."

Im confused. I really dont know if he's remorseful of what he did. How can i forgive him if he would still choose to hurt me if he had the chance to go back to that time because of that "therapeutic" sex he's talking about. But everything else is fine with us now, except for that conversation that keeps on haunting me.
