It's hard to learn the limits of what they want to discuss. You asked a logical question to a person who isn't acting that way. I hadn't had sex in 7 months, she acted like I was infected with radioactive AIDS anytime I'd try to hug her. In time she came back. Give it time, let him approach you, don't bring it up.
Remember: He's the one who "left", he's the one who needs to come back.
Resentment occurs when we aren't doing what we need to care for ourselves, though we expect others to do it for us.
