I am really in a dilemma. I dont know what to do????

It's a difficult situation you are in and one that probably won't have a brilliant outcome if your friends are stubborn. I would explain two both of these friends that you are not going to take sides between as both are dear friends of yours. Tell them that their arguement has nothing to do with you and they should not expect you to take sides! I expect they are feeling that you are disloyal but explain to them that both them are important people in your life and do not wish to lose either friendship - if they are real friends they will except the situation you are in! Hope it works out!

That's a hard situation to be in. Their attitudes seem to make it impossible for all of you to do things together and it seems no matter what you do someone will end of feeling hurt, particularly if they feel left out and learn things from a third party. It's a hard thing to do but maybe honesty is the best way to go. Sit them down and tell them that you still value their friendship, but that you aren't taking sides. You still want to be around both of them, but they are both making the situation difficult to impossible. They need to either sort themselves out so you can go back to doing things in a group or accept that there are times when you will be with one and not the other. They should understand that they are putting their friends in a difficult position and friends should not do that to each other. I hope things work out for you and your friends.
