Coming from a woman, from what you've said I would either say she is a real gold digger and only loves you for your money.. OR she has absolutely no knowledge about jewelry and what it costs. Think it through bud, make the right choice that will make YOU happy. Whatever that is I'll back ya.
This is just my like dream romantic fantasy lol.. I would be so toutched for a guy to buy me a ring that he can afford, small, nothing crazy. But then also buy some hets or small morphs that the investment will grow in over time. When we produce visuals or supers or whatever it may be I would just die if he took the profits and bought something really spectacular to go along side the smaller ring for like our 5 year anniversary or something. Sorry for the mushyness lol I'm a girl, but I love my snakes! hahaha
