Do you count this as cheating?

In an effort to send myself photos of my 8 month old son from my husbands phone, I came across a secret email account and awful sent messages on his phone.

Through different moments of time before we were engaged, while engaged, while married, and in the first months after our son was born.. I realized that my husband would occasionally email with random girls and send them dick pics, basically "sext" with them but via email.. and they'd send HIM nude shots back to him. It would only go back and forth 1-2x with each woman and then end.

He NEVER met up with them.. this was purely via email occasionally.

On my end, I'm devastated. I totally look at this as cheating and a complete betrayal. He's completely apologetic and regretful. Trying to "win me back" and prove that he's not that guy and that he wants this family.. but how would I ever trust him? He's currently sleeping in the guest room while we continue to co-parent our baby.

What do you think?
