Abused as a child

I was abused by an older brother. I suppose I was somewhere around 6-8 years old. He is 7 years older than me. I just remember him coming into the bathroom and fondling me,and not being able to escape, everything else is a blank. I am 47 years old and have lived my life trying to ignore this fact, thinking that if I pretended it never happened I would be able to forget.

My question now is I have thought about going to therapy but my husband feels threatened by it. He has some fears and I am not sure how to reassure him that this is what I need in order to live freely, without this burden. I suppose I am also afraid to go myself, afraid that I will disrupt other peoples life. Can I get release from this on my own without going to a therapist?
