against all odds

J: I always feel a bit sad when I see young couples these days
M: Why's that?
J: Because I remember how it used to feel when you met someone new and felt so full of hope and excitement at what life might hold in store
M: Mmmn I know what you mean
J: These days when I meet someone I just think 'well this is going to end badly...' So far I've been right 100% of the time!
