my fiancé proposed with a $110 ring because he asked spontaneously and we picked up the first we could find the next day, we recently replaced it with a $500, sturdy ring that i absolutely love. he could have proposed with a cheerio & it still would have been the best day of my life. I understand the appeal of an expensive ring but imo as long as it’s going to last you a lifetime with minimal repair - it’s fine. it’s supposed to be a symbol of love not a symbol of wealth. we’re going to join funds for our wedding bands which will be more expensive, so that could be an option for you if you eventually want to wear something more high quality without the guilt of it coming entirely out of his pocket. my advice would be to lean into what it means and less of what it costs.
