On your part, you may not have made your friends and family aware of your involvement due to shame or guilt. Therefore, you may not have much of a support system to count on. Allow yourself time and space to cry. Find ways to release your pain and anger. Reflect, journal, write a blog, throw paint at a canvas and call it art. Do whatever works. Consider that you no longer have to feel guilty about being a “home-wrecker," as stated in the article "Dating a Married Man," on the Dr. Phil website. This may give you some amount of comfort.
Sever all contact. To make the breakup an easing-off type scenario is a huge mistake – it will simply amplify the agony and encourage the man to keep you on as a contingency. You must resist the temptation to pursue him, which you may be tempted to do if he is the one who broke off the relationship, suggest psychologists Carin Perilloux and David M.

Get up and get active. After the set time of mourning for the relationship is over, it is now time to move forward with your life. Consider that he has already gone on with his life. Remember too, that the end of a romance does not mark the end of your life. There is so much to be seen and done. Call up your friends and invite them out or over for a get-together. Spend quality time with your siblings or parents. Play a sport or get back into a favorite hobby. Keep on track with your yoga or fitness routine. These are great for healing your mind, body and soul.
