I terminated the relationship after she refused to get professional help for her problem with lying to be the center of attention. Case in point the mysterious and fictional Miscarriage shortly after her sister had a child. The situation was rather complex and on certain parts of it, as far as I know, I am still believed by some to be the one who caused the problem. My solace is in my happiness being single now. I may not have a divorce recognized by the cong. As someone above also said there is a grieving process don't let the different phases you go through cause you longterm damage. To me it sounds like you are unsure of whether you would like to try and get back to the cong. or not. Just remember in the end that whatever path you choose it needs to be your choice and based on what you believe. Also since you have already been away for 4 years while it does hurt to deal with people and the way they treat you think about how important the people that are hurting you are to you. If they aren't helping you as a person, do you really want them in your life? and if you dont, Then dont enable them to hurt you anymore. I know this is easier said than done. Also I would highly recommend talking to someone a therapist or someone along those lines. It can be a huge relief just to let it all out and/or hear viewpoints from someone completely removed from the situation.
