I get ill after sex! is it because he is married?

From guilt or upset?: U haven't said how u get ill. Be it psychological, psycho-somatic, real or imaginary. Anxiety, stress, upset, disappointment etc. Can all cause real or seemingly real symptoms. Asthma, migraines, abdominal pain, diarrhea, constipation, neuralgia & so on. These can be caused by wanting your affair to become permanent whilst knowing that he'll never leave his wife & children, & u can't give him up.
