...You can stop it. You can let it build and build because they won't stop. And even when you say you're not interested, and they'll keep going, don't be afraid to break it down to them that you're not interested. Be stern but don't be harsh.
The reason I'm saying this is because lately this year I've been stalked and received love letters from someone I BARELY know from my old high school. After going back onto Facebook (I've avoided it for months on stress related issues), I was receiving multiple love letters from the boy saying things like 'I've always thought you were beautiful' or 'I'm madly in love with you'. At first, I was very confused. I didn't know the kid and didn't know what to do. So I wrote him back saying I wasn't interested nor I felt the same. A week later he send a lengthly letter saying how I was the one for him and that he doesn't want to be with anyone except me. That was beyond creepy. But what's even creepier is that he found my Instegram account. I never give out any of those account on FB and only send it to my close trusted friends or family members (I don't like having people from my old high school spamming me). So I finally grew some and send him a letter on why I wasn't interested, how I'm not the one for him, and how what he was doing wasn't romantic. Thankfully, I found out how to block someone on FB and Instegram.
This is why I wanted to quit FB in first place. Guys like him trying to swoon and hook up with you, it's not romantic in any way shape or form. I know it's never nice to tell someone is a freak or acting like a creeper, but in cases like this, you need to be stern in order to get them to leave you alone. Tell them what they are doing isn't okay and that they need to stop. No matter who it is whether it's an old schoolmate or someone from your work, it's okay to alert them that their action make you feel uncomfortable and to let them down easily.
Just don't do nothing about it.
