Ask her.
She dated a friend of mine in the early 1980s. I know she wasn't a lesbian then.
Your male friend must know what a lesbian's lifestyle is and he must feel if he loves you enough he can change who you are. You have to communicate properly by spending sometime alone and letting him know the truth.
If you are straight then it doesn't matter if your friend is a lesbian and you can love her in a different way such as being a sister. Make sure that you are honest with your friend and let her know you are not at all interested in have a romantic relationship with her and that you would like her to respect your wishes or you will have to end the friendship. Once you have rules between you and each of you knows where the other stands then you can love her as a dear friend, but do not discard her as a friend simply because she is a lesbian.
Their age is still young and they are still growing and learning about them self. If they are lesbian then maybe someday they will tell you and it would be appropriate for you to accept them.
The only way to know is to ask her. Or better yet, giver her some space, and let her come to you.
There is nothing special that you have to do to support your friend who thinks she might be lesbian. Just be her friend and have the same relationship with her that you have always had.
u go for another kiss ..lol
You ask her.
err...without you knowing or your friend knowing>?? she cant be a lesbian without knowing...attraction comes naturally, she has to know - she can always go to a strip club and check if she gets horny. however she doesnt have to tell you.
Haha ive done that for a friend. Well I told the girl my lesbian friend liked alot about her and how shes a good friend and she likes her and everyday the girl would go to me to hear about my friend until I shoved them together! lol im a match maker(:
'Ex' means that relationship is over and there is no need to tell your ex boyfriend you are a lesbian. However, if you want an honest friendship with your friend then time some private time out for the two of you and let them know just who you are. If they are a good friend they will stick by your side and if they don't then they were never your friend in the first place.
