💔Boyfriend all of a sudden broke us off😑

My boyfriend of what’s going on to be 3 years, suddenly put me out his apartment & “kinda” broke up with me. He told me that I was childish for not cleaning up after his grown a** 21 year old sister & her girlfriend after they crashed at our place for free for about a week. I didn’t even respond I just packed all my things like he wished & left.

So, the next day he doesn’t text me the whole day until around 5pm with a simple “bae”.

So i responded “WTF do you want”. Then like, 5 mins after i get no response, i happen to be looking at his sisters insta story and i see my bf & his long time ex.. laughing it up on there with a couple more of his sisters. (He says he didn’t know she was gone be there, yeahhh right..)

I checked him on it, & he just says that I’m assuming things and immediately throws the whole relationship under the bus. Me, being an adult and “kindly” asking if he had a new woman ... he can be totally honest & Just leave him alone. He says “No, but since your assuming I can’t put up with you anymore” i simply said bye & tadaloo.. like fr.

Then, he hits me up talking about we ain’t breaking up but you have to learn the “hard” way, so I immediately get irritated because if you love me like you claim you do, then why are you threatening the whole relationship & basically pushing me away.

I’m sorry this is sort of like a rant, please umm.. advice plz? Before i lose my mind.
