"you're wallowing in some womans boobs"
This should be an Olympic Sport IMO ;)
OP was a bit TL;DR to be honest. As with all of these posts, we only ever see one side of the argument - yours- and can have no objective measure of the strength of the relationship between you.
Basically, life is too short to wallow in self-pity and to chase someone and try and make them conform to some kind of ideal, to change them, to make them love you. Cannot be done.
Reflect on the good times, remember them fondly, wish them well and move on.
