I kinda think that you should convert only if the religion you're converting to speaks to you. LW1 seems to be thinking about it only in terms of logistics (Shabbos, and keeping kosher) and habits (not going to the two religious services she's been attending all her life) and not in terms of actual religion. Also, for someone who's thinking to convert because of her partner, the letter seems strangely devoid of his opinion. Have they talked about it? What does he thinks?
