Most Helpful Guy
Make sure you two are together with no other people around since that might lead to awkwardness. Then you should just be honest. Tell him something like: "I like you. A lot." Make sure it's not something like: "You are such a nice friend and I like you." Because this way it won't be clear whether you're friendzoning him or not.
If he responds well, you could also ask him on a date, "Would you like to go on a date with me tonight?" but always look at how he respornds, he should at least smile when you tell him you like him.
If you have been friends before, this could be confusing to him and it's best to give him some time. If you don't know him that well and you just are interested in him, he should have no problems with going on a date with you.
Also, it isn't weird for guys when a girl takes the lead. It's hot. Hope this helps!0THIS IS NOT RELEVANT ANYMORE
