How can I put this Aries in his place in a clever way?

So I’ve been having a fun, casual, relationship with this Aries man. I enjoyed us meeting up and having very passionate sex. I can honestly say the sex is amazing. But I’m starting to feel like I’m taken for granted, I can’t explain the feeling. Like I know it’s casual but I feel like he sees me as a guarantee and doesn’t appreciate my time and attention. When we are together he’s the one saying how much he has missed me, he’s very passionate, got a little upset that I didn’t say I missed him back, so I had said it not to hurt his feelings. When we text which isn’t often he wants to call me baby, his boo, etc. sends me kiss emojis. I even gave him a bday gift just cause I love giving and I found out it was his bday. During this pandemic I checked on him just like I checked on anyone else I know, I text him and said “I hope you’re doing ok, please stay safe” cause I genuinely care and was worried, his business is still open, but he never checks on me. I would also ask every once in awhile, how was your day today? He never does that. But yet he doesn’t want me having sex with another guy. If I catch a attitude with him cause of how he acts, he wants to be sweet calling me pet names.

I guess it’s the Aries in me that wants just a little attention. I know he’s not my boyfriend but he wants me but isn’t giving me the attention I want. So now I feel like he expects my eyes not to wander, thinks I’m not gonna go anywhere. How can I show him that I’m not just some girl that needs him? That I’m better than that? I want to do in one a clever way. I’m even considering ending it and I want to go out with a bang. A part of me doesn’t want to end it cause the sex is so good, but if I don’t end it, is there a way I can put him in his place without us falling out? I am a customer at his business so I don’t want to do anything too mean. Any advice? Aries men seem complicated.
