What type of relationship does Eveline have with Frank?

and
Frank have an interesting, unclear relationship. We learn early on that Eveline seeks escape.
The death of her mother has left her as the sole caretaker of her father, and her one living
brother is no help. She feels trapped, and Frank represents a way out. She dreams of leaving
with him to go abroad and starting anew.

There is not a lot of information
about Franks feelings toward Eveline; we get the sense that he is looking forward to a future
with Eveline, but whether his feelings are deep and long-lasting arent known. When Eveline sees
the ship that they are supposed to leave on, she becomes overwhelmed at the prospect of actually
leaving her father behind. He is not a nice man and she knows he wont treat her well, but she
had promised her mother that she would care for him and the home after her mother died, and the
reality that she is now facing hits her hard. Rather than moving forward toward a life which
could grant her freedom, she chooses to stay and fulfill what she sees as her obligations. Frank
is confused and then upset, but again we dont get insight into whether this will be a major loss
for him. As for Eveline, although she is resigning herself to an unwelcome fate, she is
practically emotionless as she and Frank separate for the last time.
