You turn round and take my as piecing now and the pattern you have seen before is likely to repeat. It's not until you hear him talk you through his failings and the you he is committed to change (failings and change you agree with and accept to be sufficient) that you can really have joint goals for him. You will need joint goals for you too. You both will need to buy into these and work together on this.
Obviously, he has no talked through his failings properly yet. Also you reconciled after the last PA - yet it happened again. You seem to be someone that is smart enough to learn from previous mistakes so just do what you are doing. Be kind, validate and stay detached. Don't let any manipulation take place, that includes intimacy that is too soon. Not sure when is good to relent on this but I'm sure there's plenty of advice on here on that.
