Please help, My Hubby cheated just 2 days after our wedding

I got hitched on December eighteenth and I figured out yesterday that my spouse had intercourse with another lady on December twentieth.

We didn’t go for our special night until the 22nd and I can’t accept he was letting me know he cherished me and sleeping with me when he cheated two days after our wedding. Only two days! He couldn’t even wait for me two months, two days. How would I manage this? I’ve moved out of our room and now staying at an extra room. I chatted with my mum about it and she said I should  forget him. Is this what I am going to face until the end of time?
