Hello Yumi
Sorry, i was away at the weekend so could not reply.
I hope you are feeling OK
I think it is difficult for a lady to accept that a man may care very much for more than one lady. This is a very common situation. I know T cares for you very much, but he has long history with Na.
I hope you can be patient and let things work out. I know it is very hard, but maybe you can become peaceful about it. No-one can tell the future, but you are a kind person and to be accepting of the complicated situation is very good right now.
I will think of you and hope that you can feel happier and enjoy being with your friends when T is away.
All the best
Gordon
