Is my crush’s girlfriend insecure about me?

So I had a “relationship” with him before he met his actual girlfriend. We never dated but we was hanging out, kissing you know. Until he surprisingly started to date someone else and of course that broke me into pieces. Had no choice but to accept it and I tried to just ignore him stop looking on what he post and just continue with my life. He never blocked me or deleted me tho yet he spent his time watching my stories. Anyways, so out of nowhere he deleted me, found out his girlfriend made him do it and two days later his girlfriend throw shade at me on instagram saying I’m ugly and that Im traumatized of her and accusing me of being the side chick. She also claims that I messaged him and reacted to what he post which is bullshit cause that was before she dated him and he did the same to me, and also claimed that he doesn’t even give an f about me which sounds stupid if she’s sure about that, then why the shade tho? Why she coming at me then? Anyways, he blocked me and yea the reason is because she made him do it.
