Do you believe in 'faking it 'til you make it'?

I don't think that feeling will follow. Maybe you should take some time off. Go to the doctor's to see if you are diagnosed with depression, or maybe your love life isn't that thrilling. Just recover first, then see if you still love him. If you still don't have feelings for him, then you shouldn't probably be with him anymore. Good luck and I hope you make it through.
