those who got married through the shidduch process…what made you sure your partner is the one for you?

hello! F early 20s here and total newbie to the shidduch dating system. parents are baal tchuvas so i don’t have much guidance from them, and the person i’m going out with i met through a friend, not a shadchan, so not much help from there either. i’m just looking for some guidance and reassurance that i’m not head over heels for the wrong reasons😆

also, if anyone has any good books or online resources for shidduch dating that can help cover what’s necessary to talk about and just in general advice, i’d greatly appreciate it! thank you!!
