Lovelife and Wealth: I was born on August 13, 1990.

Hi. And i am working at the same establishment for three years now, but recently, i was thinking about looking for another job. Is it fine to look for a new job at the moment?
And my boyfriend was born on February 9, 1988. We've had a really bad struggle in our relationship these past weeks. I actually am considering he's my ex now since i broke up with him. Should i still hold on to him? Or should i just let him go?
Please help.. Thanks
