My husband cheated because of me.

I(31F) met my husband(33M) when I was 19. He was my first (and only) boyfriend, boyfriend. We got married last year on our anniversary of meeting.<br><br>When I met him I was a cocky confident girl. I knew I was pretty and I used my looks to get what I wanted. I loved the attention and I would always go out of my way to make sure I was the focus. Three years ago I was diagnosed with a chronic illness. It unfortunaly causes me to a lot of weight and left me with a disability. I’m not the pretty girl I once was. I know I’m not ugly but I’m definitely not what I once was. <br><br>I admit that I stopped putting in the effort to take care of myself after I was diagnosed. I stopped wearing makeup and my hair would be a mess. I stopped taking care of myself. I felt like I lost myself and my confidence flew out the window. <br><br>I found out that my husband cheated last weekend. I was devastated. I’m so lost and confused. I did everything for him and stood by him and never thought he would do this to me. I miscarried twice before we got married and it was hard to see him take it so hard because he wanted kids. The miscarriages left me with infertility. We talked about it multiple times before we got married. I did everything to make him happy. I would always be all dressed up for him. Everything I did was for him. I thought he was happy until I caught him in bed with another woman. <br><br>He confessed that he did it to get it out of his system. He said he was stressed with work, me losing the babies and then my disability. He said he never loved the woman. She was just a hook up he wanted to get out of his system and never wanted to do it again. He said he realized he couldn’t live without me and wants to stay married. He said he was so stressed and didn’t handle the stress well. He said he wants to go to therapy to make our marriage better. <br><br>I don’t know what to do. I still love him but I can’t seem to trust him. Should I let him go and risk losing him forever? Should I stay and leave myself open to more hurt? I don’t know what to do.
