There are two sports I can do well now which I could not do six years ago (before we separated) and I would not have had time to do when we were married (he made sure all my time was accounted for one way or the other). One of the spurs to leave was thinking that I wanted to visit a certain part of the world and if I stayed married, I would never be able to do that - at least, if we did, he would plan the trip to death and I would not enjoy it.
Unfortunately legal fees have bankrupted me for the moment, so my travels are a way off, but there are other things to do.
Your desire to be yourself is not burning strong enough to get you out the door, but it is there - it is that little flame inside you that knows his behaviour is wrong, that you are unhappy, and made you post here. Nurture that flame, be conscious of it, because it is that spirit of life in you which will get you to a better place.
What you are running through in your head - anger at yourself, fear of being lonely, guilt at what people might think if they knew the truth, blame - these are all limiting beliefs. And the point about a belief is that it feels real, but it is not necessarily true, and/or it can be changed.
Anger at yourself can be changed to compassion for the girl who grew up in an abusive household and the woman who had no template for a healthy relationship. Who tried so many times to get on her own feet but did not have the right support and boundaries (because of her upbringing) and fell into the hands of unscrupulous men.
Fear of being lonely can be replaced by the belief that the world offers many possibilities, not all of which -indeed, few of which- depend on being in a relationship. It can be replaced by the commitment to targeted therapy to heal from domestic abuse.
Fear of not having children - which is the unspoken one here, I think - can be replaced by a realistic exploration of the options as to what you can offer children already in the world; or acceptance that your mental health and well-being is the most important thing and what will be will be, the future may or may not hold children for you. Having DC gives xH a huge amount of leverage to keep pulling me into court and mediation because he does not accept DC boundaries either.
I know you have said TTC is on hold, but there must be an element of fear that if it does not come off hold, and you leave H, then the chance of DC also goes, or at least gets smaller. (The other thing is that your desire for DC is something your H can use, for example above in the thread where he started talking about future children just after you raised the fact that he was abusive)
The belief that others will judge if you leave the marriage or that you are letting them down. This is easily changed by accepting that you are not responsible for others’ emotions. And really, most people will get on with their own lives because that is what pre-occupies them day to day.
I cannot remember the point I was trying to make when I started, sorry.
