How do I proceed? Just back from Retrouvaille.

Talking about how you feel is fine AS LONG AS you aren't accusing him of making you feel that way.

Once you start accusing or he feels that you are blaming him, he will turn nasty. Instead say... "I feel hurt and sad since he left. And I understand why and how you feel."

Validate and don't accuse.
