I haven't posted anything in a while, so I'm not sure what kind of help I'll get, but here goes...

My husband and I have been "at each other's throats" now for about 6 months. He claims he's under a lot of stress at work, but I've had a gut feeling that there's more to it. He claims he quit making plans to spend time with me and the kids because everytime he does he ends up having to work. But when he makes plans with his "coworker" their plans seem to happen. It's pissed me off on multiple occasions, and I've been having trust issues ever since.

The other day my dog got ahold of his wallet and all but ate it (she's an English bulldog lol). I thought it was funny till I found a note from his "coworker". I didn't get the chance to read what it said so I tried to hide it from him so I could read it after he left for work (not saying it was smart but still). Well I gathered everything else from his wallet and handed it all to him, saying that was all I found. Well before he left for work, he went to looking for the note, saying that it had an address for a "potential employee" on it and that he needed it.

Considering I tried to hide it under my phone, I claimed I just sat my phone down to gather everything that was on the floor. Well because it wasn't all tore up like some of the other stuff he kept in his wallet, he accused me of trying to make a bigger deal out of what was said in the note. Thing is I hadn't even read the note...his reaction to the whole situation, has me on edge.

He claims he has nothing to hide, yet he changed his social media password; claiming everytime I got on there it would kick him off. We used to sit in the same room and either both be on his profile or on mine, so I know that's not a good enough reason.

This is the text he sent to me yesterday:

I am sorry life has been rough, there has been alot on my mind, I do love you with all my heart, I just don't know who I am anymore, I don't feel like I am doing you and the kids any good, I am always working, I am never around and I don't feel like that is fair, that is why I am in a slump but I am sorry, i do love you, just don't know what to do

After reading it, my first thought was: which of his little girlfriends told him to say that?? When I didn't reply he sent this:

Well have a great day, didn't mean to intrude, I guess the relationship is farther gone then I thought

I feel like I've been reading to far into things, so before I get myself all worked up, what would yall think? Should I be worried? Or is he trying to be sincere?
