Some men have a fatal flaw. They look for damsels in distress to save. They want a relationship with women that will depend on them because they feel inadequate, are lonely, or have some manhood problem for which they feel they must compensate (ie. their mommies emasculated them somehow).
Most men naturally want to be protective and chivalrous. Some take it too far and look for broken women which only results in broken relationships. Men who build relationships on the need to be needed doom themselves to failure.
Two reasons: 1. If the woman never gets better and always remains distressed, the man will always have a less than adequate mate. There will never be equality and rapport. 2. If the woman gets better as a result of the man's efforts, she may realize how inadequate he was to be with her in the first place and then leave him for greener pastures.
It is a no win situation.
As a divorce attorney, I have seen this scenario play out all too often. Note, the roles could easily be reversed with the same consequence. Women will latch onto less than adequate men in the hope that their love will change the bad boy. All too often they are wrong and end up with bitter disappointment.
The divorce lawyer says, don't be a fool in love, find your equal not your inferior if you want happiness and success in relationships. If you insist on being a fool, consider that bringing children into the unhealthy relationship is akin to victimizing the innocent.
If you have found yourself in this type of horrible situation, there is hope--get the courts on your side and move on with your life to better things.
