Look, we're very happy that Ariana Grande has reached a supreme level of maturity where she can appreciate her ex-boyfriends for teaching her lessons in life and love, as advertised in her song Thank u, next.

Unfortunately though, for most of us, talking about ex-partners can result in a sudden eye-twitch, outburst of anger, or floods of tears, which is why we think it's time to introduce a little closure to our lives.

Do you have an ex-partner that you can't get out of your head? Is there something you never got to ask or say? Maybe you are just looking for some closure? Then we want to hear from you. 

Dockland, a new online factual strand presented by RTÉ Documentaries, are making a series featuring people who want one more chance to sit down with their ex and hash things out.

Maybe this will be an opportunity to figure out where and why it all went wrong or perhaps you'll finally get the chance to get some things off your chest.

If you and your ex have unfinished business, please contact Sinead.Kennedy@rte.ie
