That is so wonderful, Lazi - I really hope things work out!
Here are a few small edits:
Thank you for coming into my life
and giving me joy
Thank you for loving me and
receiving my love in return
Thank you for the memories
I will cherish forever
Thank you for the moments
I spent, lost in your eyes
Thank you for the places
Where I held you in my arms
Thank you for the smiling, ever-glowing lips
I kissed so tenderly
Thank you for the days and nights
We spent, and will spend, together (<-- this is to maintain the rhythm)
Thank you for showing purest love in a hopeless time
Touching your skin makes me fly high
Thank you for being the "Liebste"
I'll always be loving you...
Good luck, my friend.
