Millennials are known for going after what they want! We hardly take no for an answer. But if no one has told you before, allow me to be the first to tell you that sometimes you probably should...
When it comes to dating, there is absolutely nothing wrong with wanting who you want. However, remember that your method of pursuit says a lot about you. You may think that you're showing your love interest that you're genuinely interested in them and that you'll put forth all the effort they require to secure a date with them, but what you're really doing is annoying the hell out of them! Granted, everyone loves a good chase every now and then; but always consider the fact that your love interest might be running in the opposite direction to get away from you - not for you to run behind him/her.
Yes, there is a such thing as "playing hard to get." But, with your constant and predictable practices - lacking spontaneity and originality - you make yourself hard to want. You become someone to laugh at, and that's not fun at all.
Genuine interest doesn't have to be forced. You don't have to text your love interest at the same time everyday, saying the same things over and over again. You don't have to try to entice them with explicit pictures or shady Snapchat posts. When you're genuinely interested in someone, things flow naturally. Even if there is absolutely no chemistry between you two, things will still flow naturally!
Everyone wants to be loved. Everyone does! But, don't rush it.
All I'm trying to say is that if they keep telling you "no," there's a good chance that they're really not interested.
