I told him over a week ago that I would be home today and I just wanted to spend the whole day with my DS and DH.
I am just sad bc I was really looking forward to this family time. He knew how I felt and that I didn't care what we did today as long as we were all together. This is also not the first time he has done something like this. Guess I should have expected it.
To me, this is the bottom line. It sounds like the OP told her husband that she'd like to spend the day together, and it doesn't sound like he disagreed. So, what he was doing on his time off (and no, I don't suspect an affair) isn't really the issue. It's the fact that she said she'd like to spend the day with him, he either agreed or said nothing (and in this case, I'd say silence implies consent), and then he simply blew her off with some pretty flimsy excuses. If he didn't want to spend the day with his wife and son, he should have said so, instead of acquiescing and then disappearing. That's a pretty immature way to handle the situation and I hope none of our MANLY MEN (no quotes!) here would do that.
Again, if I didn't lay out specific plans, not just a general, I would like to spend some family time together on Sunday.....IMHO, I really have no right being upset if he did something else in the morning.
See the quote above. She didn't say "I'd like to spend SOME time together." She told him she wanted to spend the whole day together. He has a right to decline, but he needs to man up and use his words instead of just running off.
