This whole Ryan & Maci and who they are dating thing is pretty hard to keep track of. It seems that for a moment they considered getting back together which may be why she was reluctant to put a label on her relationship with this Taylor guy.
However now it doesn't look like Maci and Ryan are trying to get back together at all, she is now a lot more open about her latest beau. He is still a bit of a mystery though, since I haven't been able to find out too much about him. Maci sure does seem smitten, that's for sure.
