In her life, every girl goes through a phase where there are too many proposals are thrown in her face, from admirers, stalkers, not-so-serious guys, friend-zoned guys and etc. But we also have said NO to a person who you really like as a friend or more for personal reasons and felt like crap for the next week for hurting them.
Have you gone through such experiences? How did you end up avoiding their approach?
If it's some guy looking for time pass, then girls are too familiar with how to avoid them. But what if its a serious guy? One with the personality you like but can't accept because it'll complicate too many things. How would you tell them the news without hurting them much?
