I think I'm too lazy to try online dating.
Why do you think you're too lazy to try online dating?
I just don't have much free time to set up a profile.
It sounds like you're very busy, not lazy. Try to find the time to set up the profile and find a date.
I just ended a five year relationship and I'm not sure that online dating will be right for me.
It's scary to try new things and dating again after a five year relationship has ended is certainly scary. Give it a try, you never know what will happen.
