One of the crucial things in a relationship is happiness. If you want your man to be happy and head over heels in love with you, you need to boost his ego.
Tell him that he handled something important very well and pat him on the back.
When he fails to do something, don’t mention it when he is nervous but try to say it in a subtle way when he is in a good mood.
The most important thing is that you handle all of the things regarding him in a witty way and don’t let him know about that.
Trust me, all these small things will mean the world to him and you will keep him next to you forever.
