It sounds like a fifty fifty split to me. He might just want to be friends with benefits… But the last part of your message makes me think he might be developing feelings for you. The hard part about this type of thing is what type of guy is he. In the beginning in seems like he just wants to be friends with benefits but seeing his mom and hanging out with you and your daughter hints at something more.
