Please somebody reply.... its killing me inside ...?

I'm so confused. I know this is going to sound stupid but well I think I might be in love with two guys. When I was little and all the way growing up I was crazy about like guy Dan, but he is older than me and had a thing for my sister. I got extremely depressed and after a while tried to kill myself. It was a complete fail and I'm better now. I loved him so much. I stared going out with this fantastic guy who made me feel beautiful and confident and I have been with him for two and a half years. Recently I decided that I didn't hate Dan and started talking to him again. It wasnt ling before I remembered how he makes me feel. Dan gives me butterflies and makes me go red but josh is my best friend. I am so confused. Dan isnt perfect but has always been there for me but josh is. I don't know what to do. I don't even know if Dan likes me that way. Help. Please. I'm so confused. Any answer will do. If I'm being an arrogant ***** tell me. Please xxx
