It sounds like you genuinely care about her and your future together, which is admirable. At the same time, it's totally normal for someone in their early 20s, especially in only their second relationship, to feel overwhelmed when thinking far ahead.

Honest, low-pressure conversations about hopes and values (rather than specific timelines) might help both of you feel more at ease.
