The guy I’ve been seeing has an ex that is off the handle, should I do something about this?

*This ex had been giving him issues before we started talking*

We’ve been only talking for about 2 months and things have been amazing. He’s always followed through with his word and he’s never given me a reason to not trust him in the short time we’ve known each other (we have very close mutual friends and I trust their judgement on this situation). We mutually want to take things slow and get to know each other before we take the next step.

However.

He broke things off with her a few weeks before we started talking as friends. She went all over the place and didn’t handle it well. I’ve seen messages she’s sent him about demon pacts and everything she’s doing to get them together. My accounts are public but I have a very private way of posting. I can only assume she found me by going through his posts and likes. Her profile picture is still of them both, all of her posts these past several months have been about missing him and then turning around and posting him on the “are we dating the same guy” pages and blasting him all over the internet. But he is a well known guy in his hometown. Everyone I’ve ever asked about him has had nothing but good things to say about him.

But her latest post has been about an ectopic pregnancy with him.

We’ve been very open and honest about what we want and boundaries. I didn’t feel comfortable with him communicating with her and he respected my feelings about it. He has had her blocked since she found me on social media and that was 2 months ago. But this.. the ectopic pregnancy is much. Slamming it all over social media and only allowing certain people to see it is wild to me. I feel like it’s not my place but this is getting entirely out of hand.

I do not think he is going behind my back at all, he is an incredibly honest guy and mutual friends have witnessed all of the behavior.

Thoughts?
