Before one even considers entering this morally complicated and most difficult of dating arenas, one must first at least try to be comfortable with the complexities that will likely loom. These can include any/or all of the following: (a) Married men rarely reveal their affairs to their significant others so you will probably have to be content in remaining a secret. In some cases this is a preferable option anyway. (b) It is useful to ask yourself why your chosen man is entering into this type of arrangement and if it actually indicates an emotional problem in his personal dealings. If so, you may find that a certain lack of honesty in communications is forthcoming. (c) If you continue the dating in the long term be aware that it is unlikely that the status of your relationship will change significantly whilst he remains married. (d) The very fact that he is essentially being unfaithful to his spouse may indicate that you will be in line for such treatment as some stage in the future. Consider carefully. (e) Time spent with him will probably be limited as he learns to juggle the commitments in his personal life. (f) An additional challenge that may directly affect you is how to organize your emotions and psyche in order to be able to handle the unique stresses that this particular scenario presents. You require a certain type of stability in order to successfully date someone who is married. (g) Be aware also that even if the dating relationship deepens and proves to be a happy one, it may be difficult to share the joys of your partnership with friends and family members. Expect a certain amount of resistance from some parties and it certainly pays to be prepared for the possibility of this occurring. But take heart, love comes in many guises and simply because it may run contrary to typically accepted social standards of morality does not mean that it will not work out. Marriage should never be an eternal trap for anyone if they are unhappy in this state, and it certainly shouldn't preclude one from seeking fulfillment in the arms of another if needs be. From experience I can categorically state that dating a married man can prove to be somewhat daunting to successfully co-ordinate, yet if a love is true and strong enough it should provide sufficient substance in order to protect and nurture the relationship.
