Am I wrong for being honest

So my bf has a good job & gets paid every week . His mother works in a hospital she makes good money too but she keeps asking him for money ever since he has a job and he’s frustrated she keeps asking him for big money . $500 , $150 etc and usually when she ask she says don’t tell me you don’t have money either. He wasn’t replying to my text so I just said I’m going to watch a movie & sleep. He told me I’m selfish for going to sleep he said im stressed and that’s all you have to say like what.. he wasn’t even texting me back and he wasn’t venting to me either he said what a bf or gf is supposed to do is listen but whatever gn man I’ll handle it & he literally didn’t say anything but my mom is asking me for money again like damn. When I responded he didn’t . He wasn’t venting he wasn’t telling me feelings he wasn’t telling me anything but she’s asking again then he wants to flip it & make me look like a bad gf and tell me I’m selfish like wtf 🤦‍♀️🤦‍♀️he’s ALWAYS trying to make me look bad and I am so tired of it. How am I selfish he was telling me the same thing last night and I told him it isn’t fair you need to talk to her and tell her no because you have priorities and you need to get yourself together first and he had an excuse for everything . “ she’ll be mad as f” “ she’ll argue w me” she’ll this she’ll that! Like ok then let ur mom bitch you for the rest of ur life. I didn’t say that last line to him but I was thinking it. I told him again today you need to let her know you need to take care of urself first or else you’ll end up giving all you got. & he’s trying to make me look like a bad gf and saying idgaf about his problems & how he’ll just keep everything to himself like wth stressing and calling me out isn’t gonna change anything. Stand up for yourself 🤦‍♀️🤦‍♀️
