Is this possibly it??

I believe I’ve posted about this before but my boyfriend and I have been talking about getting married but for the past few weeks almost every time we talk he’ll ask me if I still want to get married. I tell him yes and ask why but most time he says that he was just wondering. The other day we were talking and he said that he saw a future with me and I asked him why he kept asking me that again and he said it was because he loves me. I don’t know if this means he’s planning something soon or what but it’s kind of irritating tbh.
