If you could send your ex any message, what would you say? Would it be a heartfelt declaration of love? Or an angry rant?

We often stop ourselves sending such messages - be they texts, emails or letters - despite knowing exactly what we would say.

And one man has created a public Google spreadsheet where people are sharing the ‘things I wanna text my ex today.’

From the emotional to the hilarious via the relatable and the outrageous, the responses make for fascinating reading.

What’s more, the spreadsheet has captured attentions around the world - hundreds of people have now added their messages.

Even more people have been sharing the spreadsheet, enjoying reading the messages even if they haven't submitted their own.

Here are some examples:

“After you broke up with me I went into your pantry, a sobbing mess, and took your nutella lol”

“I love you”

“Can you tell your mom that we’re not getting back together so she will stop texting me on holidays?”

“I miss our apt, our dog, our life together. I like to believe you are happy and wish you all the best. I will be there if you ever need me. I love you”

“My cat is better company. He may not satisfy me sexually, but neither could you.”

“I'm glad I slashed your mattress and spray painted "cheating scum" all over your walls. Also I want my f***ing Smiths shirt back”

“Why would you ever have started this and made me feel like this was something special when you were just using me to go and date another girl?”

“You’re incredible and I’m sorry I broke your heart”

“I didn’t go out for drinks after the 4th of July party. I went home with your brother”

“I still love you so much. And if I got the chance, I would be with you again and again in a heartbeat”

24-year-old Sean Peter Drohan spontaneously decided to make the spreadsheet on Valentine's Day, giving people the chance to share their reactions and advice too.

“It was Valentine's Day, and that's a complicated day for people. So I was glad to make a little space for grief and celebration,” Princeton University graduate Drohan told the Mail Online.

The spreadsheet has drawn comparisons with the Instagram account ‘texts from your ex’ which, as you might expect, shares entertaining screengrabs of texts people have received from their exes.
