Is he manipulating me or just trying to hurt my feelings?

met him about 11 months ago, relationship has been rocky from the get go when we're well we are extremely well and when we aren't we are terrible bad and mean to each other but we seem to not be able to stay away from each other.
he did something that made me upset and we stopped talking for one or two months, yesterday he sent me a vid when i opened it it was him fucking a girl doggystyle and said "wish it was u" i replied "honestly fuck you :) i hope you die" he left me on read for a few hours and then replied "lol, what a psychopath" i didn't reply. it's not the first time he does something that aggravates me only to try to downplay it and make it seem like i'm overreacting. like what's the point?
