My bf's baby momma posted about me online

My bf hasn't been with this woman for the last 10 years, he has her blocked on everything, but still pays monthly child support. She stays away other than bad-mouthing him to people.

I knew her from years ago, before he and I got together so she and I have a friendly relationship and we have each other added. Absolutely no beef between us.

My bf really went above and beyond this Valentines day, it was super romantic and you could tell he put a lot of effort into his gifts. Me being mushy, cringy and in love posted about it on my stories.

Yesterday after watching my stories she made a post about how men are trash, spending all their money on women but not caring for their kids. Saying her daughter doesn't get birthday, Christmas gifts or child support (it's a lie, he's now using my Venmo to forward her his child support money) but they have no problem being all in love and spending it on their partner. She called him disgusting and many other stuff. She deleted her post after about 30 minutes and just put a very cryptic but direct sub afterwards that sounds like it's for me.

Mind you, he asked to take his daughter to lunch so I could meet her but said only if she came also....ummmm what?

Not really looking for advice, I guess I just need to rant.

Edit:

I have her on social media because my mom used to work with her and we've always been friendly. She hearts my stuff and comments as have I for years and years. Like I stated, we have no problems, we are friendly towards each other.

I would never purposely flaunt stuff to make other women insecure, I'm not that type of person. I'm so drama free to borderline boring..

Given she's had multiple relationships throughout the years I didn't even factor her in. I highly doubt I have to curate my social media to not offend a relationship that ended more than a decade ago. It wasn't even on my mind.
