I believe communication is a good start, and honesty..also self searching, ask yourself why or what brought you to this point.I hope you find this, and if you do love this person, try to make it work, if not I would just be honest with them, sometimes the truth hurts but I'd usually the best thing
Sounds like your relationship ran its course for you. The "in love" feelings, intense attraction, excitement, butterflies in the stomach only last for at most 2 years. During that time your brain is bathed in feel good chemicals. When those chemicals go away, and they will, you are left with reality. Just know that no matter who you are with, reality will always hit, and unless you want multiple 2 year relationships like George Clooney, some self examination is called for. Be honest with yourself.
Well lets get one thing straight....you don't love this person. You may have feelings for them but love is a decision. Sounds like you've decided not to love them so you should end it so that you're not stringing them along.
