Coronation Street star Jimmi Harkishin has said that Dev knows Sunita doesn't love him.
Viewers will see Dev tell Sunita (Shobna Gulati) that their relationship is over tonight. Dev makes the decision following a conversation with Stella (Michelle Collins) last week in which she revealed Sunita would never love him.

Sunita tells Dev how she regrets cheating on him
Speaking to the Radio Times, Harkishin said: "The problem is that he's already promised Sunita that he'll sell the shop and the house and that they'll move with the kids elsewhere to start a new life where nobody knows them.
"But when Stella questions his decision, he puts the ultimate question to Sunita: he asks her if she really loves him."
He continued: "There is great sadness when he asks her that question. Dev's not stupid, but Stella's asked him a question that he already knew needed to be asked, but it's sometimes easier for other people to be frank about it. If he doesn't ask now, it will be asked a few years down the line, when the fog of love has cleared.
"He wants to know the truth, beyond how much he adores her and how much of a wonderful mother she is and beyond him understanding why she did what she did with Karl. He just wants to know whether she loves him, but she can't say that she does."
However, Harkishin revealed that Dev doesn't actually intend on ending their relationship.
"When he says it's over, I think what he means is that the idea of them selling up, starting somewhere else and living happily ever after is over," he explained.

Sunita in the Rovers Fire
"He's not doing that anymore because now he knows it's not real. He realises that they'll leave the Street, uproot the kids miles from home and yet she's still not going to love him, so what's the point?
"What he's saying is that he'll carry on, he'll still love her, but he can't give everything up for her. If she doesn't love him, he can't leave and go and live with her because it hurts and he'll constantly be looking over his shoulder wondering what's going on."
Sunita will soon find herself trapped in the Rovers Return fire which breaks out tonight.
Speaking of filming the explosive storyline, Harkishin said: "I can't think of it as being as big as it actually is – it's really overwhelming! I just have to knuckle down and give it my best. It's a massive privilege because the writing is so fantastic.
"Filming has been hard though – we've been doing day and night shoots. So it's been difficult and certainly the hardest thing I've done."
Coronation Street airs these scenes tonight at 7.30pm and 8.30pm on ITV.
