Do you think that's true if there is some major disagreement in future plans like in my situation? I am questioning it because choosing to marry him would result in the loss of being away from my family, my hometown, and my friends I've known since childhood. If I didn't feel as if I had to leave behind something so important to be with him I wouldn't feel such strong doubts. However if I don't choose to be with him I will feel the devastation of loosing the only person I can imagine myself with and resentment towards my sister especially for her conflict with my boyfriend.
