Advice please

I am a single mom of 2 boys and Ihave been seeing this guy since December 2017. And we originally started as Friends with benefits. But we kinda end up dating, since the day we met like every time I am on my day off we are together and yea we do have crazy hot sex all the time. And here is the thing he recently purchased a house and his been kinda talking me into moving in and having me pick stuff for the house and remodeling the kitchen and even mentioned making a key for me for the house earlier. I need an advice.What should I do? We haven’t reached the bf/gf status yet. He haven’t asked. I am so scared to get hurt again. But this guy is like 11 yrs older than me. I am 26 and his 38. No negative comments please...
