Hi,
Sorry to break this to you -but this is not the one.

If you are IN love with somebody, it differs.

When you love someone, it is for all their great qualities and to be honest, not diminishing that love -yet when you are In love -while it may fade, it is not what she is saying.

it sounds like she may be a bit over the relationship now. She is aware how great you are on paper, but is unsure if you are 'the one'.

take it from someone who knows, if they are questioning it now - it is only a matter of time, before the questions are answered and goodbye is all you will hear.
