mw13: yes, when deciding who to marry – see who person is, if similar hashkafos, you’re comfotable with person, and not un-attracted to person.
but, once you’re married…definitely how he treats you is most important, but what helps marriage is when feel appreciated and loved, and somehow chocolate and flowers speak very eloquently.
are you married? if you are a girl, i think you would understand without me explaining. and if you’re a guy, your wife would probably very much appreciate you giving her these things at times.
and by the way, neither is very expensive. one’s wife is definitely worth it.
also, according to rav Dessler – ahavah increases through giving, so by husband giving to wife, it increases his love for her.
