Translation of unvermeidlich

This is almost six hours, a long time for someone who has children and a day job. I recommend that we write eachother shorter emails and in both languages. Spanish and English next to eachother.
Let me talk about nicer things in this email. In the last mail we spoke about the poems that we have read in our last spring break. We are not of the kind who love partying all night. We came to relax.
I boarded the AA flight to Cancun, and got there around two o'clock. It was my first time in Mexico. On the same night I had a flight booked to Havana, but I did not know whether I should take it.
