"
And I can’t keep lying
Lying to myself, oh
I'm thinking that you love me right
But you never will
It’s too much to bear (Too much to bear)
So I swear (This time I swear)
That this time
This is the end (I mean it baby)
This verse explains that in her mind she believes that the guy loves her but in reality, it's not true and he will never love her. She goes on to say "And I can't keep lying to myself" meaning she can't keep telling herself that he loves her when he doesn't. Him not loving her is too much for her to handle so she has reached that point where she is officially done with him and the relationship "So I swear, this time I swear that this time, this is the end I mean it baby".
