Relationship problems. Her. kindly help.

Hello ! I understand how it feels to be cheated on and it can get truly traumatic, as real as physical pain. However, let me ask you , are you in love with her or the idea of being in love with her. I really appreciate it that you still love her but it can be pathological too like addiction, just because you can't get over the pain of separation ( which by the way can last for few weeks to months and then definitely resolves) you want to drown yourself in alcohol and smokes ? Please understand that she clearly still has front for her ex and she has stated the same for you ? Is it ok if she lies and then continues to have relationship with her ex while still being with you ? Respect her decision and honesty. Think logically , not emotionally. Though I understand it can be difficult when you are down and upset. This is a good opportunity to rethink on this relationship and see the future ahead . Sure it can cause some heartache but nothing which cannot heal.

Stay away from alcohol and substances which can alter mood, it only worsens it. Choose a healthy lifestyle spend time outdoors and with people who love you and pick up some hobbies and take a trip or just relax and stop brooding about it and pause the relationship for a while and reconsider your options . Have a chat with you fiance and see where this can lead to and what's in store for you and take logical decisions which is mutually beneficial All the best !
