While many people have absolutely no interest in seeing their ex after a break up, others are determined to stay friends.
It can be extremely difficult as the nature of the relationship changes, but one of the hardest parts is watching your ex move on with someone else.
But one woman went to extreme lengths to help her former partner, Jacob, when it came to his new girlfriend - writing her a list of tips and advice for being with him.
As well as listing some of his favourite things - including the colour red, Corona and 1800 liquor - she also listed things she should avoid.
She also gave some advice on being his girlfriend, including ignoring negative gossip about him and not being offended when he just sits in front of the TV all night.
She offered tips on hanging around with his mates and warned her to never finish a Netflix series without him.
She also gave details on their relationship, including the date of their first meeting.
Jacob shared the list on Twitter, and people don't really know what to make of it.
He wrote: "My ex-girlfriend wrote this for me and it’s literally the best thing I [have] ever gotten in my life."
Many people were slightly freaked out by the whole thing, saying that some of the points suggest serious red flags.
One wrote: "If someone I was dating gave me a letter from their ex we would immediately be finished. I would not date anyone who tweets this garbage either."
Another commented: "That’s like the kinda list I write when someone has to look after my cat because it can’t look after itself - not a grown ass man."
One man commented: "Any woman would be lucky to avoid."
Another pointed out one particularly worrying line, saying: "You will constantly hear negative things about him from other people." Omg lol! I missed that on the first read through. All you need to know right there."
But others thought it was sweet.
One woman wrote: "She knows that much about you because she paid attention because she loved you enough to want to know everything about you. I wish at least ONE of the guys I’ve ever dated would’ve taken the time to know even half of this about me. This kinda stuff doesn’t happen often enough."
