Does this sound like a good sign ?

I was talking to my boyfriend about a friend of ours and how he needed my help picking out a ring because he kept picking out very ugly rings for her. He said yeah I know. He's gonna make her feel embarrassed to show her ring off with the rings he's picking out. I said I pray that whoever proposes to me won't pick out an ugly ring. I said I fear that because I wouldn't want to tell him that I don't like the ring. He responded and said well I'm not picking out an ugly ring. You're coming with me to go ring shopping because I refuse to pick out a ring you don't like after I've spent my money. He said if you don't like it, you'll be buying me a ring. Is that a good sign saying that he's thinking about marrying me or is he just saying that because he's my boyfriend ??? We've been together two years.
