I didn't expect to make this difficult decision

It's a difficult decision. But I just can't stand it anymore.
I just feel that im not his priority. His diving is important than me.
Career is important than me. He enjoy with his diving fren more than me.
Every msg reply i received from him is so 没诚意.
Everyday i open n stalk his fb i also sad. I decided to leave him. For awhile.

This is the message i send to him.

Dbb... Jus frankly tell u,
actually i want to say sumting to u on Sunday midnight once u forget my bday.
But since u rmb, no harm telling u earlier.

I think I want to leave u for awhile.
The situation now is like making me sad everyday only.
It somehow even worst than last time when I with mr. Kok.
For one month i cry everyday before i slp. I cant take it anymore.
I think I shld not have this kind of stress also.

Before this, I was so interested in diving but now, I hate diving so much.
But dun worry, u shall continue with u passion n ur work.
My leave won't affect u much cos u still hav ur new frens to support u.
I believe they can take good care of u.
If u wan, chase me back when u ar ready, but my memory is short,
dun expect i can rmb how good u treat me last time.不然就随缘吧.
Hope u can put alot of effort n focus in ur work, until u success.
