Situation isn't really that important, no he didn't cheat on me, but it was a huge betrayal of trust. He has shown me that he will lie to me and break promises as soon as it becomes inconvenient for him to do otherwise. I have this huge fear that I will always be suspicious of him, never able to believe him, etc. He did this to me once before, and I forgave him, but never really got over it. I fear that I will never get over this, and that I will suffer for it/fixate on it despite improvements in the relationship. I told him all of this, and that I think he should look for somewhere else to live, and he did the typical cry apologize 'i cant lose you' 'best thing in my life'blah blah. To which I responded 'you can't be trusted' 'take me for granted' 'I don't think this will change and I don't feel that I should subject myself to this sort of emotional battery' blahblahblah Now: We have an otherwise solid relationship. I would like to salvage this if possible. I know this is a pretty fundamental thing, trust, but what i want to know is: have any of you ever had a successful relationship after a fundamental betrayal of trust? if so, how did you or your SO get over it?
