Does Timing Matter In Relationships?

Have you ever met someone who ticks all the boxes, you have great chemistry, you could honestly see a future with them… but the timing isn’t right?  Like maybe they’re about to move overseas for work/study, maybe they’re not over their ex - or sometimes it’s just a case of “I need time to work on myself”.  So how much does timing really matter? - and is it something you can overcome if you actually wanna be with someone.
