I just feel like crap

So I was a adopted. I am one of 7 kids lolol. I don’t have a relationship with my parents by my own choice. Buuuut that doesn’t mean I don’t like my siblings. If anything I want to know them. I found one of my brothers who I haven’t seen in person or talked to since we were kids. We’re technically Irish twins, I’m 25 and he’s 24. Anyways he called me on fb and so I answered and we talked for a while, we’ll I was talking he didn’t really say much, ( this isn’t the first time we’ve talked ) he was talking about our mother and things like that.. then outta nowhere he messages me as we’re on video call, hey sis do you have a cash app? I told him no and that id call him back. We had talked a few years back which is how he has my fb in the first place. I guess I’m just hurt in a way that he would even try to ask me for money if that was what he was doing. It’s just sad because I wanted to build a relationship with him.
