The boyfriend provides money to his sisters.

Hello, I’d like to hear your perspective on something. I've been in a relationship with my boyfriend, who is 35, for two years. He recently encountered some legal issues and is currently unable to work. During a phone call, he expressed how eager he is to return to work so he can support his mother and sisters, who are around my age. He has one sister who is married and another who is in a relationship. When I asked him about his intentions, he explained that he often sends them money for things like nails and hair appointments or gives funds to his brother-in-law to take his sister out on dates. While he has sometimes covered some of my costs during our relationship, such as meals, he hasn't offered to help me with personal expenses like salon visits in the same way he does for his sisters, especially since his finances have been tight due to legal fees. I understand the motive behind supporting his mother, but his sisters and their partners both work. It feels a bit odd to me. He has mentioned how much he enjoys providing for them so they can treat themselves, and it bothers me that I haven’t experienced that same level of support. I get that this might come off as petty, but I can’t help but feel a bit overlooked when he mentions sending them significant amounts of money, like $200 to $500, whenever he chooses. I work as well, and while I know he cares for me deeply, I would also appreciate that type of gesture. I recognize that it's his money and he has the freedom to spend it as he sees fit. What do you think? Is this a normal dynamic, or does it seem strange? Given that his sisters are married or in relationships, shouldn’t their partners be the ones providing for them? He mentioned feeling a sense of obligation to support them because they grew up without their father and he assumed the role of "man of the house."
