What do I do?

My husband had an affair and got another woman pregnant. I didn’t know until after the baby was born and only found out because he got caught sleeping with her again right afterwards. I got pregnant 2 months after he got her pregnant and we have a 9 month old together now. We stayed together and I tried to move past it all but i don’t trust him.

He says he’s not talking to her or having anything to do with the other baby. I track his location and check his phone to make sure and I haven’t found anything but I still can’t wrap my head around it sometimes.

I feel like we’re getting back to normal after all this time but can’t get rid of the hurt, how do I move on?
