Paul Brennan may have been wrongly accused by Niamh but his chequered romantic past gives plenty of cause for concern. It was not such a leap of logic for her to think Paul was up to his old adulterous tricks given he has cheated on her already. Paul has been involved in more love triangles than a singles' cruise to Bermuda.
Paul has had major (and interconnecting) relationships with Helen, Nicola, Robin, Yvonne and Niamh amongst others. He has three children to three different mothers and has certainly been a busy boy. It seems however that his roving eye has settled down and that he may finally be happy to settle down. At least for the moment!
