How to get past infidelity in marriage?

My husband is a very good man & always have been good to me. We’ve been together since high school (2011) married (2017) 5 children (currently 7months pregnant). We started to go through a rough patch after I had 2 miscarriages back to back. He wasn’t really there for me both times it happened because he was always picking fights about money & finances in the midst of me bleeding out, stressed & depressed in bed. I shut down & kind of checked out after all of that for a period of time.

Fast forward to about 6 months ago.. He started cheating on me with 3 different women, being very mean, disappearing for long periods of time, & blaming me for numerous of things that we were going through. The person I was experiencing, was somebody totally different & most definitely not the man I’ve known for 13 years. He later broke down & admitted to everything that he did & also told me that he tried fentanyl with one of the women he was dealing with. He said she pulled it out one night & did it in front of him & then started to do it every time he met up with her.

I feel like that was the reason behind the aggression, disappearing, & him being a whole different person. We have gotten better & moved on but on the inside I’m still hurt.. I just don’t show it.
