this sounds like they are each asking you to choose them over you. sadly that will never work out. I have been in the situation where my partners basically asked me to choose them and their lifestyle over me and mine. I was asked to further contribute to their life but was not allowed the respect for my own thoughts, feelings and desires. I was told that i was causing problems if i didn't conform to their wants. Eventually, I chose me over us. my heart was broken but now I'm in a much better place than I ever was with them.
You need to do what is right for you, you can't worry about how they feel about it. That may mean that you have to give up both of them.
