The actor's troubled character Ste Hay embarked on a violent relationship with nightclub boss Brendan Brady (Emmett Scanlan) last year, but he is now in a new romance with fitness instructor Noah Baxter (Law Thompson) after dumping the sinister Irishman.
Ste, Brendan and Noah's love triangle reaches its climax in next week's episodes, leaving the path open for Ste and Brendan's dark relationship to be further explored in the weeks ahead.
Speaking to BBC Radio Manchester, Richardson commented: "Obviously we don't want to rush this storyline because it is quite sensitive. We're not trying to drag it out, but make it as realistic as possible.
"Ste really loves Brendan and he's gone through the domestic abuse thing so far, and he wants to try and get away from that. So instead of reporting it and going to the police, his decision was to just leave him and move on in another relationship - which is with Noah. Obviously that relationship isn't going too well and on-screen in the next couple of weeks, you'll see the result of that.
"So over the next couple of weeks, there's going to be lots more fireworks in the Ste and Noah relationship and Brendan will very much be at the centre of that.
"And then hopefully we'll pick up on the domestic abuse [again]. There will be a result at the end - that people might be happy with, or they might not be happy with. We'll have to keep watching."
Brendan's son Declan Brady, played by Jay Duffy, makes his arrival on screen at the beginning of next month.
