Paradise - I'm so sorry you went through this.
I've been in the same situation. Petrified to say anything to anyone because I just knew I wouldn't be believed. Unsure if my limited memories of the first event were actually true (I was only 6 on that occasion, and the one person I told at the time now denies it ever happened to me), and in later events (sexual assault by a fellow student aged 20, and rape by then partner aged 24) I just felt so ashamed, I couldn't tell anyone.
34 years on from that first event, it all finally hit me - full blown PTSD, depression, suicidal thoughts, the works. Even if you currently don't think it's a trauma, it is, and it is obviously playing on your mind. Counselling is the best thing I've ever done, as well as telling DH (who knew something was wrong, but not what). Like you, I thought he'd blow up and try to do something about it, but he has been amazing actually.
It's good you've felt able to talk on here. It does wonders to really talk it through, though, with someone trained to listen to your particular experiences.
