Weird question but recently did something in my life which is important but has a sad background. I am wondering if it was worth telling to someone I am dating (someone I feel comfortable and open with but have only been seeing for a short period of time).

Basically an old gf and I were good friends with a girl in my old town. A few years ago her husband left her holding two kids and she couldn't handle it mentally. She broke down and ended up having her kids taken away from her, turned to drugs and became a danger to others. She was "imprisoned" in a secure psychiatric unit where she has thankfully being making progress. I went to visit her recently with my ex and it was good to see her, to let her know that people were there for her no matter how low she felt. Don't get me wrong it was emotionally tough to, but it was the right thing to do as she is still a friend.

Under normal circumstances I wouldn't have a problem sharing this piece of my life. But I have been burnt in the past for being honest and open and am wondering if I am setting myself up for another dumping situation. The reason I am asking is the plan is to see this friend more often to support her so its not something I can keep under the radar easily with someone I am dating, I'd be 'disappearing' off a lot of weekends.

It's all about context. I see nothing wrong with the story, at all. And anyone who'd judge negatively based on it has issues of their own. Still, I wouldn't bring it up out of the blue but rather in the context of the conversation.

I would not share that one until you're very comfortable with the girl.

That one is pretty deep.
