Taxes & Claiming HELPPPPP

Okay so I understand my bf can claim my daughter cus he supports her fully but can he claim me as well? We don’t live together anymore, he still pays my bills as well but we aren’t legally married. I’m new to all this tax stuff so it’s a little confusing for me as I haven’t worked the full year either. Only he has worked & provided for my daughter & I. So can he claim me as a dependent as well?? And do you know about how much he can possibly get that from that? Thank you so much!
