Corrie star Sue Cleaver has admitted that her character Eileen Grimshaw is "gutted" when she ruins Paul Kershaw's romantic plans to propose to her.
Eileen becomes deeply paranoid in the coming days when boyfriend Paul (Tony Hirst) starts spending lots of time with a female work colleague named Toni.
The final straw for Eileen comes when she discovers that Paul is not at work when he said he was going to be.
However, when Eileen confronts Paul about his dishonesty and accuses him of having an affair, she is left humiliated as he explains that Toni has merely been helping him to pick out an engagement ring in secret.
Cleaver told Soaplife: "She's gutted that she's ruined it. Eileen realises just how stupid she's been and that in trying to keep hold of Paul she's now on the brink of losing him.
"She desperately tries to backtrack, but Paul's really hurt by her accusations and walks out. She really feels that she's blown it and she doesn't see how she can make him realise how sorry she is."
Asked how Eileen would feel if Paul forgave her and went ahead with the proposal, the actress replied: "She'd be delighted, but she really feels that she's ruined any chance of that happening now.
"I think they make a great couple, and that is what's so sad about the way Eileen behaves. If she just sat back and took a look at what she has, then she'd just get on with it and be happy."
Coronation Street bosses recently confirmed that Paul will be leaving the cobbles this year after a series of "explosive" storylines.
