i acutally think it depends on each individual. i tell my husband all the time that if i wasnt such a strong, stubborn,loyal and supportive person, hed be screwed and id be gone. neither of us have cheated, but there has defintately been emotional and physical abuse between us because of his PTSD. it has been the most difficult road to travel, but its one that i have chosen to take because i love my husband and care for him and want to see him out of this deep dark hole. its been 3 years since his deployment and back in july was the big HIT our relationship was not ready to take. but with intense therapy for him and myself, i do beleive our relationship will survive. but it takes so much will and heart to push through. and i dont think very many couples could handle it in the long run. weve had our good times, but most definately had some bad ones too.
