Accept that it’s over
It may take some time before your heart accepts that it is over between you and your partner. In the meantime, however, try and come to terms that the relationship is no more.
Tell yourself that it is time to move on and start afresh. Take away items in the house that can remind you of your ex.
In this situation, it is also advisable to have regular chats with your family and friends to take your mind off everything.
