She met him (14 years her senior) when she was 22. They had a very intense on/off relationship. He kept leaving her then coming back to her. She was so in love with him she couldn't see the wood for the trees. On one occasion she decided enough was enough but he wormed his way back in by basically promising her that they would get married and have children. He then withdrew this offer a week later because they'd argued over which restaurant to have dinner in one evening. She then discovered that he was seeing another woman on and off.
She cut him out of her life for about 8 years and recently got back in touch with him. He seemed to be delighted hearing from her and it seemed as though she was feeling just as she did back when she was 22 and in love with him. They had a squabble about something or other and now he's blocked her.
I honestly feel exhausted telling her the same thing over and over again which is that she is better off without him and they were never meant to be. Indeed, I suspect he would have been the ultimate ruining of her.
But is there anything else I'm missing? Any resources or other words of advice? I feel like she just genuinely can't move on.
