heartbreaking lyrics / terrible advice

Call your girlfriend
It’s time you had the talk
Give your reasons
Say it’s not her fault
But you just met somebody new

Don’t you tell her how I give you something that you never even knew you missed
Don’t you even try and explain how it’s so different when we kiss
You tell her that the only way her heart will mend is when she learns to love again
And it won’t make sense right now but you’re still her friend
And then you let her down easy
