engagement or promise ?

Maxx
Me and my boyfriend picked out a ring the day before Christmas and kept saying this is a promise ring but since it was so expensive he said whenever we decide to get engaged we will use the same ring.
Well on Christmas in front of my family he was already kneeling down when I opened the ring and he said "since I'm already on my knees (he paused took a sip of beer) this was supposed to be a promise ring but.... will you eventually marry me? And fuck a promise I WILL take care of you and our son forever" (I am currently Prego) he later posted this pic on his fb and everyone is congratulating him and I'm still confused like is this really an engagement?! Or is it still just a promise ring ?! He hash tagged it it with #keepingmypromise
