Did you two get together pretty young before he had much of a chance to date other girls? The reason why I ask is I've seen a few people that got together and had kids early before they really got to date other people and then later have a mid life crisis. The women I know that had the mid life crisis started dressing younger and pretending to go to the store but actually went to the bar.
Another thing is maybe at some point another woman flirted with him maybe at a store or something and got him having those butterfly feelings like you get when you first start dating someone new. Some people can get addicted to this feeling. I know of a few people that never really had a long term relationship cause they got bored with someone within a couple of weeks after the new feeling wore off. After a while they wait for another person to come along and spark that adrenaline rush that they craved.
Definitely something that should be brought up and talked about. You two might just need to do something in your life to spark the interest back up. I would let him know that you found out about the stuff and let him know you are upset but would like to try to work things out if possible if you feel your relationship could be worked out. If you don't bring it up to him then maybe try to do some different things like in the bedroom or maybe ask about going to do something you don't normally do and see if he starts slowing up on ads and dating sites.
