The flame-haired singer has been helping his good friend try to figure out where she has gone wrong following failed relationships with several stars including his pal, One Direction hunk Harry Styles, John Mayer and Jake Gyllenhaal.
She explained: ''He says there are different kinds of love: There's physical attraction, mental attraction, and emotional attraction; there's also comfort and obsession.
''You need to have all of those things in one person. You have to mentally respect them, be physically attracted, and have a comfort level.
''You're obsessed with them, yet you also know they're going to stay. I've never had that in one person.''
The 23-year-old singer - who has previously played down romantic links to Ed, who recently supported her on the six-month US leg of her 'Red' tour - admits she is envious of other couple's relationships but that they also give her hope of finding her true love.
Speaking to InStyle magazine, she added: ''I feel jealousy, but I've been trying to channel it into mutual admiration and inspiration.
''If someone has a really great boyfriend or career, I think, it's cool that happens. Now I have proof it can happen. Maybe that's out there for me someday.''
