You started about five threads about how you don't trust this clown and about "what does it mean when a guy does/says this" because you've never been close enough to this assclown to TALK TO HIM about what it means or what he means. On and Off for four years. What in gods name is wrong with you that you would waste your emotions on something so unstable and so far away?
Get therapy to find out why you allow this idiot back in your life and then once you've figured yourself out, then and only then start dating again. If you start dating again before you work on you, then you will end up in another confusing, non-committed cluster-fvck of a game playing situation just like the one you've just ended YET AGAIN.
Your closure is you accepting that you're better off without him waltzing in long enough to screw you and then leaving you for other women close by.
YOU blocking and deleting HIM is long over due.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
