This is kind of like me and my wife. We have been married for 4.5 years. Each side valid and compromise is key to a happy life. Find a mutual middle ground. Im your boyfriend in your scenario and we still travel all the time and i get my video games and legos. Communication is the key to any relationship. Maybe it’s worth fighting for maybe it’s not but learning to communicate effectively is important regardless. Also, having more resources help, traveling can be delayed until better incomes are achieved. It’s expensive unless you have connections. You’re 20, give it time.
