He's a struggling new dad who was finally able to get this fairly secure job and is very good at it.

You're struggling also. Apparently he must not be to good or you wouldn't be venting over his mistakes and the possiblity of him lying.

Do what you have to do. As far as texting him you probably will not hear back. You said he's moved. I'd be on the phone and be prepared to again, do what you have to do.
