Some people are just so scared of relationships and they run away as soon as things get serious. Some people are just too lazy and unloving and so, once the puppy phase ends in a relationship, they stop putting in effort. And they end up feeling empty one day for, such people are the ones who take things for granted, who can never love anyone seriously and truly. And there are others, who over think and end up destroying the relationships.
We can't please everyone in life. If you know what you're doing is not wrong, If you're not hurting someone, If it's not really wrong then there is nothing to be worried about. Let's always give more and expect less.
