i do find if someone has been through similar experiences to you then they are more likely to ‘get it’ - two friends of mine who have been great have also had their fair share of break ups to navigate.
So true - I've fully explained everything to three close friends now and I can really see how their views are driven by their own experiences (all very supportive, just with different insights!). Also, @Whatdirection, please do use this thread as your sounding board whenever you need it

You desperately need to take some space for yourself here to have a long good think, away from this awful cycle which you've (very insightfully) identified as preventing you from properly reflecting. That's an excellent "need" for you to have, and raise in your next counselling session.
I really do, and have no idea how to get it. Last night, after a really stressful day with my daughter (who is very skilled at pushing boundaries at the moment
) I said to my husband that I was going to go sit on a bench down the road and listen to some music once she was asleep. I thought that would be somewhere safe to go as he would know I was close by and not doing anything dodgy. This caused a huge issue for him though, because he was a) worried I'd be calling the OM and b) was worried it meant I needed space from him and that I was going backwards in finding any connection with him. It was hugely stifling to be honest. I know it's my own fault for having the affair, but there's nowhere I can go now without being hounded and quizzed and it makes it not even worth going out.
We've had a tough day today as well and I said I need some mental space if I was ever going to move forward, and we couldn't think of anything I could do or anywhere I could go that would give me peace and quiet and that he'd actually be able to manage without panicking that I was up to no good!
@Peach1886 it sounds like you've found some really good clarity around your boundaries and next steps! How is your husband responding to the points about his behaviour, is he seeking help or is he just going to make attempts to be better?! Honestly a day out and about by myself sounds amazing, but there's no way I could have it for the reasons mentioned above.
@Alcemeg ah, my sister is a mature adult, just very shy and unlucky in love! I really don't think she's the right person to be talking to about this, on reflection (and after that disastrous attempt!). It's made me even more reluctant to try my mum because we just don't talk about things like this. I will stick to my friends I think :)
@QuentinBunbury they did go on a walk but he definitely didn't say anything. She's the loveliest lady, but a bit 'daft' in the sense that she doesn't really pick up on nuances or anything like that. Needs every aspect of a film plot explaining to her, etc.
Therapy is on Thursday, will be interested to see what happens as we're still kind of stuck in the same cycle I've already described.
@FoxgloveSummers your beach analogy was is absolutely accurate!!! How do I break the cycle?! I just don't think I'm strong enough to actually make the leap 
So just as you can say no to his persuasive and convincing arguments that he needs something, you can say no to his characterisation of you as uncaring (just another way to get something from you).
Yes, I agree. I do try to defend myself but of course his answer is to point towards my affair as the prime example of how uncaring I am towards him. We are just going round and round in circles and it always comes back to me not bothering to try and fix the marriage, ditching him, and deciding to put my need for 'cheap thrills' ahead of our family.
