[Lucid:]

My husband really likes to have time to himself, especially when he's stressed out about school or work. If the stress gets bad enough, he'll stay up until 4 or 5 in the morning, long after I've gone to bed, just to have some alone time. It really worried me at first, but after discussing it with him and figuring out that's what was going on, it doesn't worry me as much. Him staying up until 4 or 5 still never makes me happy, but at least I know he's just playing video games for hours on end to relax, and not hiding something.

Don't talk to him about it while he's out playing in the garage, that's probably the time he's least likely to open up about it. You probably know the best times for you two to talk about things, but over dinner and right before bed are usually good for most people.
