Choosing between guys...

I'm in a wonderful relationship with a guy I've known since I'm a little girl. We've reconnected seven months ago and have been inseparable ever since. He is everything I've ever hoped for in a man... 
Just this week, an old friend came back into my life after a little over a year.. We weren't in contact for so long because of a fight we had. I have been in love with this guy for years, and he now tells me I'm what he wants. 
I'm having a hard time choosing... Any suggestions?
