I need advice me and my boyfriend have been together for 7 m

I need advice me and my boyfriend have been together for 7 months and for Christmas he gave me a bridal set but said that were using it as a promise ring because all the promise ring that he looked at he didn't like any of them but the bridal set he did what I don't understand is why he wants to give me a promise ring or a bridal set but yet I have asked him 3 times to move in and he says he will but he hasn't yet so what does this mean

Also I don't understand that we thought about moving into his ex wife's house instead of staying at my house and he was so eager to up and move there ASAP but to move into my place he said that he would like to wait at least a year before he moved in with somebody I feel that it would be better if we moved in together and seeing how things were going to be to see if we should still stay together you know if things would work out or if we should move on
