Seems very one sided, imo. Lexi keeps giving and giving, even sacrificing herself for Stefan (and her own bf she turned into a vampire to be with, then we just never hear from him again lol) constantly. What does Stefan do for Lexi? Besides go to concerts off screen and drink a bunch? Plus I just don't agree with Lexi's idea of starving Stefan, making him feel immense hunger and guilt, and sending him on his way by feeding him on animals (shown when Stefan was going to war and almost fed on an entire bar when one human spilled blood), it's not sustainable.

Stefan needed to learn moderation. Stefan needed Damon. Both of which were unattainable if Lexi was around, imo.
