Sometimes it needs a lot of togetherness. And at some other times, relationships need space to grow,to have a perfect relationship with your partner, you and your partner need to understand how to give space in a relationship.
True love is blind, some say, but true love too can get boring over the years if neither of the partners have nothing new or unique to share. And the closer you get to your partner, the more of your individuality you will lose. Spend every single day with your lover, but spare a day or a few hours for yourself in a week.
