Is he cheating?

I personally don’t think I’m overreacting as I have justification for my reasons, here we go.

I’m in the shower and he’s doing his hair, he tells me “I’m meeting with Eric tomorrow for Pappadeauxs at 1pm” (this restaurant is very nice and pricey, it’s a southern restaurant. Your average ticket is gonna be about $40+ that can even just be for one person. This bothers me because he has NEVER taken me out to eat, we get the food and come home, he has only offered on my birthday, only on special days where he probably feels obligated to, and I’ve told him no and explained why I said no (I’m a reassuring person, I communicate very well). So I know who Eric is, as they have talked on the phone and they sports bet together. His reasoning for Eric WANTING to take him out is because he gambled & put Eric onto money that he needed, and in turn he’s taking him out? That’s kinda contradicting.

We’ve been together 2 years, our lives together is boring. We have a 10 month old, we don’t go out, he’s very selfish in the bedroom and doesn’t last long and has never pleased me, he doesn’t want me to leave but yet literally won’t talk to me about my feelings or how my day was..

Why do I think he’s cheating? It’s a nice restaurant, he is always caught texting other women and liking their pictures over the last 2 years (even after I gave birth, I stayed and cheated back to get even and he doesn’t know- I know it’s not right but I hate being betrayed because you literally could have just fucking told me, especially when it feels like I’m pulling teeth for acceptance.

Should I pull up at the restaurant and see for myself? Do my thing? Like?? I just hate how much I’ve invested and if he’s doing anything behind my back, I so badly want to catch him.
