if you like him
and you wish he was yours but you and him are still friends and you know his wife or girlfriend you can understand by kind of backing off him like making sure it don't look like you like him or you to or together
You just don't. If consider him your best friend you definitly wouldn't want to do that to him, and just to be straight-forward, she's with who she's with for a reason. So why hurt your friend relationship for someone who's not promised to be there like your best friend is?
Be honest and straight forward, yet tactful and tell your best friend you would like for you both to escalate the relationship to a higher level.
Does your friend know that you are gay? Are you truly best friends where you can talk about anything? IF so, try this: -tell your friend that there is a woman at work that who is attracted to a straight woman and she asked you for advice. See what her reaction is. If she is positive about it, and gives you an example of what to say, then you are ahead of the game. If she becomes very uncomfortable and negative about it, then question yourself whether or not its worth sacrificing your relationship with her by telling her you true feelings. IF she is a truly good friend who understands, then she should be understanding to you, and just say "thanks".
* Since you are her best friend you would know if she is bisexual or has lesbian tendencies and if not, then don't risk telling her your feelings as it will cause tension in your relationship. Straight is straight!
Its not considered Lesbian, its called Bi maybe shes still attracted to guys
Your straight friend will not be interested in a gay relationship, I am sure he/she knows that you are gay, you will risk a good friendship if you try and make unwanted advances, so you have the option of finding someone who is also gay and would love to have a sexual relationship with you as long as you practice safe sex, all will be well.
It will ruin our friend like relationship
If she is your best friend than just straight up tell her.
YOu get a Gay friend the same way you get a straight friend. You be real and open.
with your best friend
If you like him then go on ahead and start on the path to a great relationship. If you dont like him then tell him straight up b4 something bad happens and you lose a great friendship/friend.
we'll the good thing is to tell your best friend and see how he/she goes with it
