What I would do if I was tied between two guys would look at the pros and cons of each of them. Decide which of the two would be best for you and go from there. Love is hard sometimes. Good luck to you!
It depends on how old you guys are and how deep the relationship is going. If you are like 15 and we talk about going out to movies and mcdonalds afterwards and a kiss on the cheek at your door: date them both. But if it goes deeper you'll have to make a decision or you might lose both.
I think you should think what one likes more of the things I like and you should think who is sweeter who is more romantic and who do I feel more comfortable with ect. Tell ur self I'm going with this guy well then does it feel write ? Then say I'm going with the other guy wat one feels write?
If, at 11, you're not allowed to date, there may not be a real issue. Maybe, you could be friends with both for a while. Enjoy playing the field if you are allowed to date! (Just don't be intimate with either.). You have a long time to do that stuff later. Enjoy being a kid while you can.
I am kind of in the same situation and it is hard to choose.... but, choose the one who makes you special.... and do they ever talk to you or anything?? Also.. just pick the one you could see yourself be with... Hope I helped (=
