Unfollowing ex on social media?

It’s been 2 weeks since we broke up. I’m a bit annoyed and now thinking about things I put up with it’s like I want my control back. Lately he’s been hitting me up. He texted me saying the couple we met said hello to me. Then he messages me on instagram commenting on my photos like 🔥. Yesterday he messaged me saying I’ve seen that one before your dress 😇 Nice nipple action 😝. I said You could’ve just said I looked nice. And no you haven’t. He said you do look “nice”. Like I’m just like annoyed with him and also like is he trying to get back or just trying to be a fuck buddy? And then thinking of all the times I was gaslighted and just the unnecessary fights. We broke up also cause I wanted him to meet my friend and he said where are we going to meet ? Who pays? And it was crazy to me because his birthday last and I spent $800 on him and for him to say this to me. He said I’m uncomfortable paying and how I can see her alone. So it’s like eww.
