To add a male perspective, I'd say all the ladies answers are true...there's a need for more info here, but if he says it's not you, & not to take it personally, I suggest you take it at face value...but to get to the heart of the problem, he's gotta let you in...& that's something that's very hard for a lot of guys to do...remember, we've grown up with all the mostly BS images of what makes a man a man...men don't cry, & definitely men don't cry for help...even if he's bleeding to death inside...
