The way I see it...if blondie was a true friend to your ex then she would never jump into her bed whilst its still warm...and you would never have posted this question if you had no intention of going for it ...so all these morals that are allegedly making you uncomfortable..are really ...your genuine guilt at feeling the way you feel....that doesnt mean you are doing a bad thing. It just means maybe your relationship with your ex was never quite all that you hoped for..for whatever reasons
Do what feels right..life is a journey and so short...good luck.
