"Please help! I found myself desiring my husband's brother"

From a female blog reader:

Am inlove with my husbands brother,I use to dream of him and have sex with him in The dream too but I think he does not find me attractive because he likes slim girls. I have even been working out because of him and I think am doing well .I have once poisoned the girlfriend the day she came visiting with him but the poison was not to kill her but give her serious running stomach when she was kissing him in my presence with no respect at all.please how do I make him notice me? I don’t need all your judgemental comments please my husband and his brother are same . Just advise me on how to get his attention. Thanks
