trial question

in canada, i have a trial coming up for domestic assault aNd assault by strangulation my ex accused me off after i got arrested for smashing a window to her apartment when she kicked me out, i suffered abuse from her the entire relationship and never hit or choked her once, i have a photo of her coming at me with a knife ( the same knife that she later stabbed me with and the police have the knife for evidence, i also have 2 videos of her punching me, a video of her admitting to throwing glasses at my head and a picture of a black eye she gave me, she has absolutely no proof besides her mother claiming she seen bruises on her before… how likely am i to be convicted if i have show all of of this in trial and prove she was really the abuser
