Help! I'm in love with enlightened man
If he is really enlightened, he will not be interested in you (romantically). If he is interested in you (romantically), he is not enlightened. The Pali suttas state:

It is impossible for... whose mental fermentations are ended to engage in sexual intercourse.
Sutava Sutta

However, he could show friendship (metta) towards you. True spiritual friends (kalyanamitta) are difficult to find in the world.
