Hi everyone, so I know I probably sound like a whiny child ( which I'm not)

Anyway I like this guy have done for about 3 years now we're like best friends we did also date previously for ten months, he's become really difficult to handle lately sleeping with nemorous girls pretending he doesn't want to be in a relationship with me😞

But on Tuesday evening (this week) I'd been going through some rough patches so he came over and he said he'd date me again if I got the old me back, my friend also likes him and has been seeing him so I don't know what to do

Please help x
