It sounds like he's not being straight with you. I think your "gut" is probably telling you something. Probably you should take a step back and look at the relationship and where it is going. You've been dating for 7 years. What's next? If it's not the right thing for you, you should move on as disruptive and painful it might be. If you want to make it work, you should sit with your partner and open the lines of communication so that you're both working together for a shared future instead of sitting on a gut feeling of suspicion.

I would normally go with my gut instinct, but a Dave and Buster's Card? I'm wondering more about how you found the card in his jeans. Did you suspect something was going on with him; hence the need to search his jeans, or were you simply doing laundry and emptying out his pockets?
If it was instinct that made you search the jeans, clearly you think something else is going on, so continue to go with your gut and get out. Otherwise, I really don't see the need to make a big deal of it especially with no other signs of him cheating. Good luck with whatever you decide, and update us if you have a minute.
