Splitting the bill with my bf/his son. And Hypocritical play time?

Question

So my boyfriend (of 8 months), his son and myself went to get food. 
The bill came up and he's tight on money, so I offered to split it. But when he handed the waitress the cards he told her to put himself and his son on his card and I just pay for my own. That's not what I meant by splitting it. 
I don't mind taking turns paying. but any time we go out to eat with his son he doesn't let me help pay for anything the kid eats. We've already talked about it I don't remember the verdict, this is the second time it's happened. it kind of sucks because I don't mind helping? Just makes me feel excluded. Am I over stepping?
....
 He's also been kind of uptight with how I play with his son this past weekend too. But he plays with him the same way so it's kind of hypocritical. I know people are particular with their kids so I'm not even upset by it, but I kinda don't understand when were talking about getting our own place? What happens then? Am I just not going to ever watch his son? That's not realistic. (We have a roommate rn)
I've helped raise my siblings and he knows that. He's never seen me interact with other kids before so he doesn't know how I am with kids.
it's hard for me to figure out the boundaries because it's like one things okay one weekend then the next weekend it's not. And I know he has all the right to set those boundaries, it's just confusing because they constantly change person to person/day to day.

Answer

You worrying about the trivial. As a women you should focus on yourself and let that man take care of his responsibilities. Its his duty as a man to take care of his son.... and you only been in this mans life less than a year.  Parents need to monitor and watch new love prospects and as far as i see youre in a probationary period. And youre asking for responsibilities when u as a women should be observing him as a man and making sure he is a adequate life partner that could potentially be your childs father. Let him carry his load and handle his weight. Its already enough that he didnt pay for your meal and u begging to pay even more🧐. If u get pregnant or try to build a life with this man u need to make sur he is fully capable willing and able to handle his responsibilities as a man so just observe him instead of intervening.

It's been 8 MONTHS. That's still an extremely fresh relationship. Especially for one involving kids. This soon into dating, I'm surprised youve even met his child. Much less regularly hang out with him. 
I'd stop and remember that this is all new. The relationship is new. Dating someone with a kid is new. Dating someone when you have a kid is new. 
It's odd letting someone in on your parenting. He's used to doing it all on his own. Both the good sides- like playing. And the bad sides- like paying. Take it easy, and remember this is a journey and takes patience and time to adjust 
I'd just say 'id love to treat you 2 to dinner tonight!' or 'you drove, how about I pay?' or something like that. Make light of it, not an issue out of it. He's uncomfortable letting someone step in, but you can try gently easing him into it and making it the norm. 
As for playing with his son, as long as you *know* you aren't being innaproprate (too rough/ect) and you saw him doing it the same way, I'd mention that. 'sorry, I didn't realize I was playing innaproprately, especially because I saw you do the same thing with him once. I thought it was okay' or something. He might just be a bit overprotective right now and not used to others interacting with his kid yet

Answer

I only met my fiancé’s child after we were together for a year. The fact that you’re already having dinner with his child, shows a certain amount of trust. Focus on yourself, if the child is in your life a lot, have a good conversation with your so. Set those boundaries together to avoid conflict. That way you know what’s up, and he knows you take it seriously.

Answer

Better than the other one way round. Imagine if he expected you to pay for all his sons meals.  Maybe he doesn't want his son to be a burden?
