*shrugs*
if you ask anyone to write it they would write it like that, but if you dare to write that on your test, chances a teacher gets mad are pretty high
the correct spelling is:
Ik houd van je
(the "d" in the dutch language is very important cause we have the rule that if the stem ends with a -d, the third person singular gets the curious extend of +t, in other words it's:
Hij houdt van je (he loves you), that's the famous -dt rule that people still don't get right the entire time (one of the most difficult rules to get according to profs))
