Am I the side chick?

I've been dating my boyfriend for almost 4 months and I recently started going over to his house. Now I can definitely be overthinking but I've dated plenty of guys and I know a single guy fridge when I see one. He's one person but his fridge and pantry are FILLED with food. A lot of food for a single guy.... He has a son but he only has one kid and he's 14 and he only has him every other week so why does he need that much food during the other week? Idk it just seems sus. Every guy I've dated (who was actually single) had soda, hotdogs and a few random items in his fridge. Never a full fridge. I did make a small comment about it and he said he doesn't eat out much and sometimes his son and randomly stops by with his friends. I don't know. It just seems sus because again this is a LOT of food. Even for a grownan and teenager
