loving yourself should be more than you Love the other person, before getting committed to anyone think will it be long term/ short term there is no use of regretting later, everybody has their own circumstances or liking which may sometimes go out of your liking which you cannot control for sure, Try speaking to the person you like if he/she is redy to get back then it's okay or else let it go.
if a door is Closed try knocking it, if it never opens then MOVE On, That's Life.
why do you need someone else to make you happy . Self love is the first step if you do not love yourself how can you expect others to love you understand that you are unique in your own way and that is best and the strong part. If you will search for happiness in others you will get dependent on them and as they leave it will break you into pieces so please understand youself try to do the things that you love or gives you peace or satisfaction . It will lead you to greater heights. The moment you give the authority to someone else to make you happy now the power is in someone's else hand and it's very dangerous because they will use it the way they want it to be. You are more than enough for yourself love yourself embrace yourself .........God bless you
