Just try to move slowly and see what seems right to you. Some people enjoy online dating, others hate it. Some try to meet new people through hobbies or interests that they may have, but maybe neglected when they were in a relationship. Think about what makes you happy, make time to do those things that you like to do. Staying happy and feeling good about YOU makes you 100% more attractive and approachable to other positive happy people. If you aren't ready, give yourself time to heal.
