You really just seem like you are doing whatever you want to do and then making excuses as to why you couldn't DB or why it was OK to go against DB. IMO, you are only hurting yourself in the long run. At least be honest and admit what you're doing. I've been separated for four or five months and I have never contacted my H to sleepover. Never even crossed my mind. Deep down, I think that you are trying to reassure yourself and, at the same time, sabotage his GF. Totally understandable under the circumstances. These sitches just totally suck. But, please take an honest look at what you're doing. It's time for some greater self-awareness. You can do it.
