No he's not jealous at all I don't think.
When they were kids (which pobably wasn't that long ago which show he's mature alot i guess)they loved each other, but it was an innocent love, not the kinda love that was: "every night there was a new girl sitting beside me in my car," and so they grew apart and he probably ran into her again lately and she's married and has kids and stuff and leads a great life, that why she's everthing, and since he's has none of these he's "not anything" I don't think he's as jealous as he is sad that things can't be like it was when they were young and innocent.
Or at least that's how I see it, everyone probably has their own interpretation, that the beauty of music and this website
