Now I know it was me all along that wasn't worth it.
To sort of piggyback on Oakleaf's response,

No, no, no. If you weren't worth something to him you two wouldn't have ever been friends. While it hurts excruciatingly bad right now, it sounds like the romantic chemistry you hoped for wasn't there for him. Has nothing to do with your worth.

Others here have offered some good advice. Take extra good care of yourself. Cry yourself through boxes of tissues then go do something nice for yourself. {{{hugs}}}
