Perhaps this is a natural progression in healing.
Initially you probably couldn't have just said - well i'll just let that go for now at least, it would have seemed unnatural and you would probably fight against that.
All the work you have been doing sorting this out is coming to fruition I think.
I like LifeRecovery's description of "resulting integration".
You don't really need to hold on to the past or the fear anymore because you know how to protect yourself and you are doing that. Isn't it great! I'm happy you are feeling lighter.
