Not enough understanding. Thats all I can say. Maybe you 2 dated
before you 2 had a chance to get to know each other better before
deciding to date? It occurs for many couples and both side are have
responsibilities towards the relationship between themselves. It
takes 2 to make it work, not 1 loh.
If you found it strange why only 1 side is contributing and nth
from the other side, you can more or less know this relationship is
going nowhere.
Next time when anyone meets a person he/she likes or feel attracted
to, STOP!!!
Make friends 1st, then get to know that person better. Know much
about that person, behaviour, likes and dislikes, patterns,
characteristics and traits. THEN decide should the relationship go
further than just friendship level to "better friendship" or deeper
relationship.
