I am married woman having 3 years old daughter. Recently I got in touch with a boy from my college who had proposed me for marriage 10 years ago. I always liked him but did not admit at that time and we forgot each other. He is married now and having two kids. Even then, we are attracted to each other mentally and have started missing each other. How do we go away from each other now?

If you really want to go away, then break all means of contact. Both of you can agree upon this and stop contacting. You may find it difficult initially but time will drift you apart in absence of contact. Most of the time I have seen that people attempt such kind of measures only to resolve their guilt and are never interested in breaking up the contacts. I suppose, you are not one of them!
