the counsellor is not going to solve this , you are, the counsellor is there just to move your feelings along so that you can see them clearly rather than them getting in a tangle in your head.
not surprised you flit from one feeling to another, its all so confusing, nobody knows how they feel and what they want. the counsellor is there to support you in this uncertain time.
go with it. be in the present with all this uncertainty. look what inner resources you have pulled on in this time, resources you didn't even think you had at the beginning of this thread.
this all takes time but look how far you have come in two weeks.
i guess you are wondering how you should play it on sunday? don't worry, whatever you choose will be the right thing.
not wanting to throw mumbo jumbo in to the mix but wearing white has the effect of 'protecting' you from others negative feelings/vibes. it serves to create a sort of boundary so you can see what are your feelings / what are his. Thats why doctors wear white coats, not to look clean but to stop them absorbing all the negativity from their patients. just a thought - I shan't be offended if you think i'm ridiculous
in between the end of one phase and the beginning of another is nothing except a mass of confusion- this is a very creative time when things happen. - this is what i got from counselling, quite a sensible counsellor too, i had counselling when my partner of 8 years left me for another woman after years of treating me badly but telling me he wanted to marry me but not yet, there were no kids involved so not as serious as your situation but counselling was brilliant. I then had it again when i had PND. another counsellor but totally different.
if you don't get on with your counsellor tell them you feel uncomfortable - they won't take offense - its actively encouraged to have an open relationship with them.
