So as the title says we've been seeing eachother for quite a bit, everything has been great by most standards. But I've just noticed something.

Back when I first met her I was scrolling through her Facebook and noticed pictures with her and her ex, back in 2018. I thought nothing of it obviously, this guy was in the past as far as I was concerned.

Fast forward to today, she just recently made an IG profile for her new puppy, and only followed 17 people, he was one of them, I could tell just from the profile pic. So then I did some digging, he's liked all of her most recent photos, and she has liked his.

Here's the bomb though, on her twitter she liked one of his tweets that was something along the lines of "So my day started with splitting my coffee and it falling down my crotch, so that's good". IMO this was the moment when I realized she has to be signaling to him or something.

Before me, she told me in confidence that she had a dry spell of about 1 year, and she's a very shy, introverted person that helps kids in need, she always is the one who reaches out to me to watch Netflix over FaceTime (COVID19 has forced us not able to see eachother for a few weeks, small detail). But recently I've definitely noticed a lack of enthusiasm, and at first I figured its just her depression mixed with this whole virus thing. But now im thinking it could partially be that her ex is starting to become relevant again.

She doesn't know that I know this, or even know the guys name, I've basically discovered this by snooping so I'm not sure how I should approach addressing this to her. What do you guys think I should do?
