right I realise this is my problem and I haven't moved on. Maybe this is the issue.
Have already posted this on chat, and thank you so much to those who replied, just thought maybe this more appropriate forum.
'for fun(ha)' I followed my ex in fb and tracked back his gf. We were together ten years ago. I do not check his fb regularly (he added me as friend, I declined, he is friend of friend so I can see for eg his friends. Obv she is one) Anyway, they apparently celebrated their 10th anni in March. We did not split up till the May. I just feel rubbish about it, it has brought up all old feelings, I had a really hard time getting over him, blamed myself, if I had said x instead of y, and all the time he was with someone else.I KNOW is ancient history, but it hurts, and I don't know what to do with it.
