Ex gf puts picture of us as her profile pic

So we haven't talked to each other for like a year or smth and I ran into her at a totally random place,

just a little chit-chat, she complimented me and I ignored. She is the most disrespectful and toxic bitch I have ever dated in my entire life and we broke up and get back together few times(I was not aware of RP then.)

​

After a month, at midnight, she puts picture of us as her profile pic and asks me "How's the pic?"

​

So the correct thing to do would be to ignore her, right? Because I am a dumb fuck I sent her a pic of me in a leash (We were both extremely kinky when we were dating). Don't ask me why, I don't know too.

​

Then she texted "omg where did you get it" and I said -name of place- and nothing else.

​

I thought she would change her profile pic after few days (it has been 2-3 days) but nope she didn't. Few hours ago she posted a story on IG with some fuckboy.

​

Should I be worried? I have no idea what her intention is. Is she trying to make other boys jealous or smth else.

​

Your help would be appreciated, cheers.
