Depends what u really looking for in the r/s ...
1) a strong bond but slow to warm up type
2) quick passionate and explosive but veyr much depend on
feelings.
If you are serious and looking for long term, I would say choose
the B loh,
Remember to be a great gf/bf, u must 1st be a friend. Thats a basic
requirement. Feelings can be cultivated, and u will realise how
much u feel for B if she suddenly out of your live...
As for A, its a wild card...it can go either way....
Good luck choosing......
