Would you consider this sarcastic?

So in March my 19 year old brother in law randomly showed up at our house at 10pm from Florida. Which is cool because it was a surprise to my husband I thought. Two weeks go by and he’s still there. He brought in a huge tub of clothes and some duffel bags. Well now it’s almost August and he’s still here. I got upset with my husband saying no one ever discussed him moving in with me. He just showed up and never left. He doesn’t have a job but collects unemployment. He sits on my couch all day and sleeps there at night. I have let it go for a while now and just let him be. His sister offered to get him a job with her husband but he refused. Even his parents defended him saying why does he need a job if he lives with his brother. At this point I’m pissed off because he’s not just going to continue sitting around my house doing nothing. He doesn’t help with anything. He’s not even trying to get himself on his feet. I finally said if he’s going to continue sleeping on my couch I at least want $150 from him for rent. I was kinda made to feel like I’m asking too much but fuck that, that’s the least he can do.

Well today he cashapped me $149.99 and I can’t help but to feel like it was out of complete sarcasm. Why couldn’t he just type in $150 and jnstead wanted to type out $149.99. Would anyone else feel like the .99 was disrespectful? Yes I know it’s technically $150 and I’m glad he paid up but I can’t help to feel like it was a joke to him.

Am I overreacting? I’ve let him live scott free for several months now. I guess this is why I’m feeling disrespected. He also has gotten upset when my husband has asked him to clean up after himself. He has said “wow I didn’t know I was a burden” and then left to another family members house for a few hours. His parents have made him into a entitled brat and they always defend him. My husband I think doesn’t want to piss him off because he doesn’t want to be the bad person but I’m tired of it. I’m ready to go home, give him is $149.99 back and tell him to leave. Would I be wrong?
