People need tough love and need to be told. No, they are not interested in you. Why would they be. Thats not being nasty. It’s the truth. Unfortunately, babying people is now the don’t thing, you can’t tell the truth unless it might upset them.
Someone very close to me was scammed. He was a real person, lived abroad and travelled to see her - paid for by her - over a number of years. He acted like they were in a relationship, she paid for him to travel with her everywhere all while he doing the same thing with other women in different places. She was highly intelligent, very senior in a very difficult job and she was really attractive - she had also focussed on her career to the exclusion of just about everything else and wanted a relationship. He came along, incredibly good looking, similar age to her, saying all the right things but the signs were there.
I knew him from a different social circle, and knew he didn’t want a relationship with anyone, he wanted someone to fund his lifestyle, which she did, because they were in a ‘relationship’. One where he lived elsewhere for 9 months of the year and saw her when she either travelled to him or paid for him to come to her.
No matter what I said, or how honest I was with her about what I knew of him she absolutely wouldn’t hear it, because he presented a completely different side of himself to her and I just ‘didn’t understand modern dating’. In the end he took 5 years of her life and tens of thousands of pounds before she realised he wanted her money, and the opportunities that brought. I lost her in my life too I think because she felt ashamed and embarrassed when the inevitable happened.
She was fair from stupid, but she was naive in relationship terms and desperately wanted to be with someone. No amount of honesty would have made her see what was going on. Love genuinely can be blind.
