forgiveness

Today I asked my husband for forgiveness for so some stupid stuff I've been doing lately and guess what? He forgave me - it felt so strange because I expected him to yell and be furious but as always he's so kind to me. He says I really didn't need forgiveness because I did nothing wrong but in my heart I feel like I did. I know my current state of mind is contributing to my actions but I am still responsible. I even prayed today for forgiveness... and it felt good. But with all that the hardest part for me I know will be to forgive myself. I don't know if I can but if I don't - I think I'm headed for real trouble.
