I'm glad you at least told your closest relatives. Now that your daughter is gone and she is the only one who knew about the situation, you at least have other people you can count on if things are getting tough. And of course you have us too.
Would H realize that you informed them? Presumably, and that certainly makes them think, seen the strange reactions.
Telling such things to someone, that is also the beginning of acceptance. Understandably, this was still very difficult for you as this is the first time you come out with this.
I must admit that my entire entourage of family and friends are aware. This is because we have a a huge social life and at a certain point I wanted to go through with the divorce. However, I am at peace with this and I do not find it difficult to talk about this anymore.
However, this is a very personal thing, I am someone who wears my heart on my sleeve, you are probably more of a person who keeps things to herself.
At any case, you have to do what makes you feel good PLC.
