AIO? Been gone all weekend

Some context:

These are messages from me (29F) and my partner (31M). We’ve been together for ten years and have four children together. I’m a SAHM and he has a good job. We live comfortably. This entire weekend he’s been leaving at odd times/going to his friend’s place. I’m a pretty laid back person—I don’t usually question him. BUT this has me questioning things. Now that I think about it, he also did this last weekend I just let it go. Reading the messages, I feel like I might be overreacting.

More context:

“The game” is slots at the corner store. We recently moved back to our home state (Tx) from Vegas after being there for five years. I’d say he definitely has a gambling problem.

Guess I just need to know AIO?
