It’s understandable that you still think about this.
Lots of people who have had this kind of experience think about it often.
Maybe you have to think about it even more.
Because you and your girlfriend are very close.
Maybe you have strange feelings when you are near her.
Maybe you are unsure if you should tell her or not.
Do you want to tell her?
Think about what you want from her when you are physically close.
Then think about what you want to say to her.
Perhaps these words will help:
Somebody once hurt me very much.
So I don’t want to do anything which will hurt again.
Sometimes I also want to stop hugging quickly.
That is because of my memories.
Not because of you.
Think about how much you want to tell her.
It is important that it feels ok to you.
You can tell her what you want from her.
