Does a married woman's admiration for her friend's husband and her thoughts about him constitute a betrayal that warrants sin and God's wrath, especially since she strives hard to rid herself of this feeling through prayer and supplication, and are there other solutions to help her overcome this painful feeling?

If a woman admires her friend's husband and her heart becomes attached to him against her will, she bears no sin for that. However, she must fear Allah and adhere to the boundaries of Islamic law in her interactions with him. This means not speaking to him except out of necessity, lowering her gaze, and blocking all avenues to temptation. If she does this, she bears no sin for what her heart harbors towards him, and this is not considered a betrayal of her friend. She must, however, resist such thoughts, because dwelling on them leads to temptation and corruption. She should also supplicate to Allah frequently.
