I cheated years ago and it haunts me everyday

I (38F) cheated on my husband (39M) 10 years ago and I can’t let it go. It haunts me everyday. <br><br>My husband and I were trying to get pregnant to no avail and I was so stressed about it. I was afraid I was unable to give him a child. I started going to the gym and taking care of myself feeling empowered that I had something to offer and being around fit people. Through one of my friends I was introduced to a guy there who I developed feelings for. It just happened without me even realizing it and before I knew it things had already gone too far. I ended up stopping it all but it weighs on me so heavily. I told my husband last year because I couldn’t carry that around anymore. He now sees me in a different way and it upsets me because I thought we told eachother everything. <br><br>I can’t change the past but I can’t get it out of my head. I can’t let myself go again because I feel like I don’t have the confidence to make him happy like I used to. I worry everyday that he really doesn’t still love me because I cheated. I know he still loves me deep down but he sees me differently now. I want him to love me like he did before. I’m unhappy.
