We have been dating for 2 years before we got married 4 years back. We have been having issues and challenges from the beginning however for couple of years she is traveling for work or busy for days, thoughts of her being with another man fill my head every day. She has been reassuring me that she is committed to me but even after all this time together, I'm unable to get rid of these thoughts & doubts. I know that she had been in to relationship with two men before she started dating me. After all she DID have a PAST legacy. I just don't know how to find sanity and control my thoughts. Building trust requires mutual commitment by both the partner once mistrust develop it require extra effort and help by skilled counsellor.
