Well friendzone sucks right? But still you love your friend more than like a friend and you do all the crazy staff with him/her while you or the other one has no interest on another partner? Well I'm here will suggest you few things that might help you to get out from the zone.
1. Have your own life.
You'll chat with them for a bit, and come for a situation where he or she will can't stop talking to you! Right at the moment try to show em that you're busy! Not in the sense of ignore. But you have to ignore. Don't show up to them for a bit. Where thatll make them feel wanting you more and they'll start to wonder that without you there's nothing he or she can do!
2. Show Excellence on hobbies
He or she might now you're hobbies! So you can use that time to improve your own skill sets, which makes them happy about you and get more attractive.
3. Follow the previously given steps!
Just keep it to yourself for a bit! She'll or he'll come back for you! Wanting you more! Good Luck!
