How do you allow yourself to heal while still in the marriage?

Guys, I’m just absolutely heartbroken and right now I don’t know what to do. My husband has lied to me multiple times throughout my pregnancy. Like I’m talking 20+ lies I’ve CAUGHT him in.... some of the lies are big, some are small. But I think I’ve finally reached my breaking point and I’m just so heartbroken and hurt. I’m so lost on how to cope with this, how to get through this. Surely some other woman has been through this? How do I allow myself to heal while he sleeps next to me every night?
