Ruth Aitken (also Fowler) is a fictional character from the popular British BBC soap opera EastEnders, played by Caroline Paterson from 1994 to 1999. Ruth was Mark Fowler (Todd Carty)'s ex-wife and she is far more comfortable with his HIV status than many of his other girlfriends. However, their marriage eventually disintegrates due to Mark's habit of shutting her out and his inability to give Ruth a child. They split and she strays with Mark's cousin, Conor Flaherty (Seán Gleeson). Her betrayal deeply hurts Mark but it also gives her the chance to be a mother as she becomes pregnant with Conor's child.
