hi, Your husband seems to be involved in activities without much regard to long term consequences. This kind of impulsive behaviour is seen in many psychiatric disorders including personality disorder. If this pattern of behaviour could be traced back to his childhood/adolescence and if it is seen in his other areas of life too, like in education, job, social relationship then chances of personality disorder are high. Presence of psychiatric disorders like bipolar disorder may many a times masquerade with these behaviour. So I would advice you to have him a detailed evaluation by a psychiatrist. Medications and therapy may help many with such problems to a significant extent, with at times leading to complete relief. So do not loose hope and visit a psychiatrist with your husband.
