Not sure what to do?¿

So I've liked this one guy (let's just say 'guy A')  for a couple months but so far he hadn't shown any interest in me.. A few days ago I found out that this other guy (guy B) likes me and so we started talking and he's really nice, caring, etc.. I still like guy A but I'm also starting to like guy B too... Should i just forget about the first one orrr? I'm just confused.
