Saw my ex bf on hinge but he has a new girlfriend. Do I say something?

Hi, title pretty much covers the situation but I’ll give some more info!

I (22F) saw my ex boyfriend (21M) on hinge today. My ex and I dated from Oct. 2024 to March of this year. Prior to and after the breakup I suspected he was cheating on me, but I had no hard evidence to support my suspicions. Around 2 or so months post-breakup I saw him on hinge, I skipped him, and moved on with my day. A few weeks later I was really going through it emotionally and looked at his Instagram, his account was private but he had an initial in the bio of his account. This made me check facebook and sure enough he had a new girlfriend. Flash forward to today, I’m doing so much better and have completely moved on. I’m laying on my couch surfing through hinge and sure enough, I see his face. The account was not verified, and I don’t remember if his previous account was verified. I immediately checked his socials and sure enough, he still has the same girlfriend. When I went to check his socials I guess I completely closed out the hinge app, so when I went to open hinge back up, the account was no longer there.

My main question is, do I get in contact with the current girlfriend? Part of me says hell no, it’s none of my business. But part of me feels for this girl, I don’t want her to go through that. I have no screenshots/screen recordings to provide. Im just really unsure about this situation and feel like I’ll feel bad no matter what I do.
