What should I do?

He cheated on me 5 months ago. We stayed together afterward, and he stopped everything with that partner. We were getting back on track, but after 3 months, I found out more about their involvement. He denied many things but accepted some. He doesn't want to leave me. He begged at my feet all night when I found out. He gave me his Instagram handles and offered his WhatsApp, but I declined as I didn’t want to be that controlling. We were improving, but I discovered he hid some facts. He admitted it, saying he thought it would break our relationship. Now he wants me but is scared to ask because he says it's my decision, and he’ll respect whatever I decide. He acknowledges that cheating was a poor choice and that I have to suffer through the emotions and pain. He says if I had cheated, he would have left me. But he shows how much he wants this relationship to work, admitting his mistakes and promising to change. He took full accountability and never blamed me, even admitting his fault to our siblings. I haven't completely gotten over it, but his genuine efforts make me unsure whether to stay or leave. My parents are pressuring me to marry if a good match comes along. When I told my mother about his cheating, she hated him and told me to forget him. Now she doesn't want him in my life. I see changes in him, but I'm unsure whether to reconcile or leave. I loved him deeply during our three years together. We had a great bond and understanding. I don’t know if I'm missing the good times and ignoring the cheating or if it’s something else. He’s ashamed to ask me to stay but wants the relationship as he lost his mother in March, and I can't see him suffer. I genuinely feel he wants to fix this. What should I do?
