ANY GUYS WANA ANSWER? -- is he happy?

I certainly don't think he's totally happy. While his life was harder with you it seems you both were happy (minus the bills). I'm not sure if it's shame or just anger in general that he doesn't reply. I was young once and did something similar to that and no I wasn't happy, just thought I would be. You'll have to decide if you want him back if he comes back at all and how to get him to work things out with you instead of fleeing the issues
