You can't choose who you love
When something doesen't work out someone says move on. They get mad if you don't take their advice.
You can't switch off your feelings. If you really love someone they will be in your heart for a long time. If you forget about them easily then you never really loved them.
You can't choose who you love. Sometimes it just happens. You can't force yourself to love someone. You shouldn't be criticized if you fall for someone who others don't approve of. Take things one day at a time and see what happens.
You will move on when you are good and ready. Don't let other people tell you what to do. Otherwise you will stress yourself out. There is a right person for everybody and love is out there. Some people just find it more easily than others. It is out there so don't give up.
