How do I know when to use seni and when to use sana?
The verb is sevmek, which takes the accusative case :D "sana" would be used for special verbs, indirect objects, and to say "to you" when describing motion.
Ok so seni here is ''you'' in accusative?
Why is it present progressive fit i do not love you? I wrote sevmim instead of sevmiyorum. I'd there even such a word as sevmim?
"sevmem" is what you are looking for.
Romantic love, oddly enough, is usually expressed using the present progressive. Why is beyond me
