It sounds like you’re in such an emotionally exhausting and difficult position. To hear you’re a year on with little movement. It sounds similar to my situation although I’ve been with my fiancée for 6 years not a quarter of a century. I really feel your pain and anguish. I’m not sure if you feel this way but I’m hoping I’ll get the partner back I fell in love with, not this nightmare of a relationship I have now. I think the lies, deceit, blaming are all so destructive of the feelings even if you love the person so deeply trust and lies just can’t co-exist, well that’s what I’m feeling at the moment. I love my fiancée but I’m not fulfilled but then feel guilty I’m making it about me!! It’s a real head mess isn’t it?! I’m thinking of going to to a group myself for support but just haven’t picked up the courage as yet
