My BF is sweet, caring and thoughtful..Yet, one of my best friends hates him.?

It depends how close of a "best friend" she is of you. If she really has your best interest at heart, she may sense something about him that is "off" or she knows his bad side. In which case, you may need to listen to her opinion to get an unbiased perspective.

If she is only thinking about herself, then she may like him or she is jealous that you have a good guy and she doesn't or you spend more time with him than with her.

I think you should ask her what is wrong. And get to the truth.

Sounds like your best friend has the case jealousy if its a male. Of if its a girl best friend, she might just not want you to be happy. If you're happy with the dude, then be happy with the dude for your reasons. The only one that's wrong here is your friend. Unless they know something you dont, in which case they should tell you.

you're best friend probably ****** him. or wants to **** him. or knows someone has secretly ****** him. or wants to **** you. or is upset you spend all your time with your b/f... just remember, that if you are a girl, and your best friend is a girl, she secretly hates you. cos she knows all your secrets and you know hers, and if either of you mess up she will not hesitate to tell everyone what you really do secretly. it's a cruel world in a girls life. just keep going out with your boyfriend, talk to your best friend and make sure they are honest, do so by getting them drunk first.

your best friend should be happy for you, unless thier one of those ppl that have a fantastic judge of character, then things are diff.

For the most part they sould be happy for your happieness.

Your not missing anything, yur friend is.
