Be there for support and a shoulder to lean on - listen when needed. Try not to get involved as this is their situation and issue that has to be worked out between those two.
cause hes a jerk
You are not a friend. If you were truly friends with that person, you would leave them alone, and let them be happy. It is very hard to find a romantic connection in this world, and you do not have the right morally to try and get a person to dump your "best friend." I suggest you move on from the person, and try to find someone else. Also work on showing some respect towards the people you call friends. I am sure you would not want someone doing that to you.
Woah! Do not do this! She is your best friend! i think its better if you tried going out with someone else! Else i am afraid you might lose your best friend...
Be someone she can rely on. She (or he) will need a shoulder to cry on, and someone who will listen to them without passing judgment
Uhhm wow... Well you should support them being lesbians.
Sure, a friend can help you.
Each person go on one side of the person and dump the snowball on their head
talk or tell someone
dump him, wait a few days. go out with the best friend a week later
A fair weather friend is well a friend that you may think is a good friend but then as soon as your life is going as bad and you need a good friend for help and support he ditches and leaves you. If not forever at least until the "weather" is going good again. Example: I thought John would always stick beside me but when I was in trouble and needed help it turned out that he only a fair weather friend.
tell your friend that its going to be okay and that your there for her always and it will pass soon
Friend means someone that cares about you, misses you when your away(best friends only) and someone that helps you when you need help.
