Blocked

Hey guys just a quickie about blocking. Think a guy blocked me as the imessage went green (in an argument!) from blue on iPhone to iPhone but when I checked the iMessage on my MacBook pro it said 'delivered' and was blue. I thought theMacBook Pro had nothing underneath the message if you're blocked? Does this mean I'm not blocked? So yeah, says delivered in blue on iMessage on MacBook pro and green on iPhone.

Thanks in advance if anyone can shed some light on this for me :) I'm not ver technical so simply saying I am or I am not blocked is enough!! CHEEEEERSSS from London!
