How can one overcome guilty feeling and live a happy life?

Hello doctor,

I am a 22-year-old married woman. My husband is truly the best in the world, always caring for me. However, I have been feeling guilty recently about some incidents from my past. During my childhood, when I was in class seven, a boy expressed interest in me. Although I did not reject his advances, I accepted his gifts. One day he insulted me, and I decided to end the association with him. I realize that it was not a real relationship. At that age, I did not fully understand love and its complexities. I genuinely believe that the only person who truly matters to me is my husband. Inspite of all this, I still feel guilty about the situation.

Additionally, while preparing for my SSC exam, I had a male friend I considered my best friend. He confessed his feelings for me and referred to me as his girlfriend. Although I did not have romantic feelings for him, I did not explicitly reject his advances. In truth, I used his friendship for study-related benefits. However, after some time, I started finding his presence burdensome. I feel guilty for not being honest with him and taking advantage of our friendship.

I am grateful that I found my husband six years ago and I love him with all my heart and soul. I have confided in him about these past incidents, and he reassured me that they do not affect our relationship. He is a fantastic person who always tries to make me feel comfortable. Despite his understanding, I still carry the burden of guilt and struggle to move on. Please help.
