What do I do?

To be honest I wonder if you actually want anything to do with either of them? You've not written any reason to remain friends with these two which I think speaks volumes. Find some people who can be as good a friend to you as you are to them.

If you details here the reason of their confrontations I give a clarified details on it. Since i don't know what is it all about. I prefer to say that, you must be aware of what is reason behind your arguments. Talk to your friends about the things he hated you. Ask him first the reason, to look for a better solutions on this matter. Good soft talk is the best things for someone to be calm and make peace. I f you know, the reason. Be careful to analyze what proper actions to be done for you and your friend be peace and avoid fighting again. If he is sensitive enough avoid stating any offending words to make him angry again. Be courteous to your friend and as much as possible, call him and ask for apology on what you is wrong even it is means that you do no harm for him...that it. I hope this little opinion I provide is helpful to you to eliminate any misunderstanding with your friends

If you want to remain frineds with both people, you ahve to put your foot down now. Tell both of them that you are going to remain friends with both and you will hang out with each of them separately. When you are with one, do not allow talk about the other. If your friends cannot stop trying to split you in two, you will have to stop hanging out with BOTH of them. You should not be put into that situation. Also, when you are with one, you need yo be sure not to bring up the other either.
