A person is with another person because they choose to be with that person. He is with his girlfriend because that is who he wants to be with. He may feel more passionately towards you, but at the end of the day, it’s a cost/benefit analysis. If he stays with her, then that’s what he has decided is most beneficial to him. Sometimes there are financial, legal, or co-dependent entanglements that make it harder for someone to leave the other person, but they still have made the choice to stay with that person.
So, for the psychics that are telling you he doesn’t care about her, well maybe he doesn’t. But he does care about whatever it is the situation with her is providing him. I think the question I’d ask a very straightforward reader (not a strict empath), is if he will ever leave her. Many psychics will not tell you the truth because that would end your need for them. This is when I’d use someone like Ness, QOC, Lady P, or others who don’t entertain a third party situation just to keep you hooked. For the sake of your heart, try to stay away from murky readers.
It’s a tough spot to be in. I wish you well.
