sende öyle Canim, sevgin karsiliksiz degil bunu biliyorsun dimi.
şu süreç bir geçsede senide aileye dahil edebilsek.... tabi zaten sayılırsında.. resmen yengem ol istiyorum.

My Try:

So are you, dear, your love is not unanswered. You know that don´t you?

If this period just passed and we could include you in the family...of course you are actually counted in already...I want you to be my official sister-in-law.

Thank you Abla

wich past is it? Conditional?

yes. conditional in simple present. -de should have been written seperate.

ho ok! Same as you said in my previous post about iyi ki attached or not?

yes similar method with both ki and de
