Rain, why wouldn't you want to delete this app? It feels like it's turning the knife in your wound? I had a letter (phone for about a couple of weeks) for him, then decided that if I was to look it'd only hurt me more. So I posted it back. If this app is making your mind runs, delete it.
I hope you are not taking it the wrong way but it feels like that you are torturing yourself when you perfectly know what he is doing. Unless he shows you his phone consider him as using this app.
