Where did I go wrong?

So I don't usually get many matches but got one this morning. I texted her first "Hey XYZ 👋" and followed with a GIF which says "How you doin?". FRIENDS fans will know this.

But I didn't get any reply and later when I checked she had unmatched me. And I still don't get it. What did I do wrong? There was no conversation at all. I have no idea.

And this was not the first time. The same thing has happened 2-3 times before too and I didn't even send any GIF at that time. I just said a "Hey" and "How are you?"

I sometimes wonder did they swipe me right by mistake or something? I don't know anymore man..

Please tell me.. anybody..
