Bressie has opened up about remaining single a year and a half after ending his relationship with Roz Purcell.
The Blizzards frontman (36) split with the former Miss Universe Ireland (26) in early 2016 after nearly four years together and despite saying in April he "doesn't have the heart" for new love, he said he believes it's his personality that's off-putting to potential dates.
When asked by Newstalk's Bobby Kerr about his single status, he said: "Because I'm odd as Christmas, that's probably the best way to describe it.
"I wouldn't go out with me, honestly. Maybe for a date or two I would, then I'd be like, 'Ah forget him.'"
He echoed his sentiments of heartbreak after their split, saying the break-up "takes a lot out of you".
"If I'm honest, I was in a long-term relationship and absolutely 100% wasn't ready after," he added.
"That takes a lot out of you, a break-up. There's no point in pretending. It's hard, it's really hard. I've been quite open about that."
He is now focused on pursuing his latest business venture, the Camden Recording Studio, which he put his energy into after his former relationship ended.
"I needed time to get myself back together and build myself back up again," he explained.
"The other aspect of it is I was training for Iron Man and my whole life was taken over by exercise and I suppose being in a relationship. I decided this year that I was going to spend time on getting all that back."
Roz has been dating music promoter Zach Desmond for nearly a year and has stayed silent on Bressie's comments.
Recently-reformed Mullingar five-piece, The Blizzards, are on the bill for this year's 3 Countdown Concert at St. Stephen's Green. Lead singer and mental health advocate, Niall 'Bressie' Breslin, reflects on 2016 and looks forward to the coming year.
