I want to forget my ex and start to love my husband

This post is long. sorry about that.

I had a bf in 2022 I loved him so much. It's like I felt love day by day increasing. our affair only had 1 yr. but at the end of 2022 his parents disagree to the affair and he stopped. But it was very hard me to stop feelings toward him. after few months like 1 or 2 he found a new girlfriend. I didn't know about that even though we stopped affair I chat with him. (actually it's like I begged for him that I need him) later he said he has a new gf. but I didn't stop chat with him. time to time I sent messages. he also sent msg to me. in 2023 june I met a man kind hearted. He started to love me. but in my mind I had feelings for my ex. last month I married to that person. he is so good. very kind. I love him than my ex. but when we start to be romantic I still remember my romantic moments with my ex. that make me so stress. I want to forget my ex and live my husband. but my heart don't allow me. so I'm suffer because of that. my husband loves me more than ex loved me. but now my feeling which I had toward ex is stronger than feelings I have toward my husband. please help me to forget ex and love my husband
