All Paths Lead to Love

Ravi and Ashwini are in love. Their houses are present in a colony as shown below. Daily after 8 pm, both the young lovers meet on the terrace of Ashwini's house and share their feelings for some time. To get to Ashwini's house's terrace, Ravi has to follow a path and jump through many terraces. One of the paths followed by Ravi is shown. Because of one or the other problem, Ravi may not always take the same path.

Please find all the different paths available from Ravi's house to Ashwini's house and convey this information to Ravi.
