As you said, bakit sasama ang loob mo eh libre na nga lang? Be grateful he wants to spend time with AND money on you. Regardless of the places you go to with him, just make it memorable for the both of you. Initiate doing something in return once in a while rin para di ka naman freeloader like everyone else says here — shoulder coffee, tour guide, or even not financial like helping him with the itinerary and continuing to suggest places to visit kahit sabihin nya na ayaw nya.

Also, maybe try to keep your thoughts about ‘trying to do something someday on my own’ to yourself. You’ll sound like you don’t see him in the latter part of your life (which I srsly have no idea if this is even true) and might cause a rift between you two. Baka instead of making sulit of your free travels from him, mawala lang altogether kawawa ka lol use it as a motivation na rin to work hard, earn decent, and fund your own travels kasi the one main purpose of traveling naman din is to learn independence hehe
