Found out about what my husband's been doing with other girls the whole time we were dating 3 weeks ago. 

Now every moment I'm concious I just see the messages I saw in my head. Re-plays of the things he admitted to me are on a loop and I can't stop telling myself I'm an idiot and asking myself where I fucked up. 

I haven't told any friends or family about what happened and I'm stuck at home all day. We just moved to a new city and don't know anyone close by. 
I've tried listening to music all day on full blast go to the gym, take long walks, read, watch shows, cook and just anything to make myself try and not think about it for one second. I just want a moment of peace. 

Last night I hugged him to feel comforted in anyway and I just started crying and couldn't handle physically touching him or even just look him in the eye. Everytime I do I just imagine things he would do to other girls when I wasn't around. 

I just want a second of peace. How can I deal with this?
