""bf, when we talked in Brisbane last year you explained to me your desire to travel Australia alone this year and I totally got it. When I talk to people about you I am so incredibly proud to be with you and of what you are doing. I also know how stressful everything has been with the sponsorship and I think you have been amazing.
In the past I have been afraid to be honest with you and voice my desires which are that after Australia we would spend time with each other and share experiences together whether that be at home or abroad. But recently when we've been talking it seems clear that your future plans don't involve me and I wanted to let you know that I understand. I understand your desire to travel alone is very important to you and I'm going to step out of your way so that you can do it.""
Well, this sounds a bit passive aggressive and manipulative to me.... How about more sincerity and directness:
"BF. I love you, I'm proud of you, I think you are a wonderful man with beautiful dreams. My dreams are different than yours -- I want to share my life with someone by sharing our adventures through it. It is time for me to start looking for that someone, and as I am a one-man woman, that means ending our romantic R. Who knows, maybe we'll find our dreams circle back to each other someday. Right now it is pretty clear they lead in different directions."
