California...?!

So, I have been offered a free trip to Santa Cruz California. I have been in a rut for awhile now, I want to say 5 months but could say 6 years. Regardless, the practical person I am is saying NO!... its an ex boyfriend inviting me. He was the only ex Ive had that there were no angry, jealous feelings with during or after... just kind of a mutual goodbye and almost friendship with benefits. We just recently started talking again and he has offered to fly me down to his ranch in cali to harvest and learn and play. What scares me is being away from my boyfriend, family, and comfort zone. I have to call him tonight to confirm the tickets and have him send them to me... havent seen him since high school... I fear he is expecting something in return, but at the same time know I am strong enough to make is clear that's not what Im coming there for. I was born in California but never had the chance to take a trip out there. I am just concerned about my anxiety in traveling alone, never done this before. I never even left to go to college bc of finances. Dallas is my comfort, but also my rut. I have been "stuck" lately. It is from July 12-19. Advice.... PLEASE?!?!?
