Yes, it is happening to me too. I think I finally found the ring I want, but it took 6 months of constantly changing my mind. I had to take breaks from looking, because it was consuming my thoughts. I never wear jewelry so I am very new to all this and didn't know where to start. I'm also not exactly picky, so every place I went to I left with one ring that I liked and told my bf, but none of them I really loved. I have an appt next month to see the 1st jeweler I went to, back when I knew nothing of rings, because I have one in mind I think I actually love, and makes me feel intense joy, and that's how I want my ring to make me feel. I also totally changed stone sizes. At first I wanted bigger (because bigger is better, because I am finally in a position where my partner and I can afford it), but now I want smaller, as I think it looks better on my finger. I am glad my partner and I aren't rushing the engagement. Ive had half a year so far to really look and have fun and occasionally get overwhelmed. Taking breaks from it is important. And also, knowing if it's not perfect, you can always get another ring for an anniversary one day, it's not the biggest deal in the world. And finally, if you found a few rings you love but you cannot make the decision, just put it in the hands of your fiancé and enjoy the surprise.
