When does someone becomes Creepy?

Luckily I have none here, all of you guys are pretty fun to talk to actually. It's the guys who dont take no for a answer and call your family members when nobody gave em the number. those guys. xD Creepy wise not much bugs me personally. They could tell me they wanted to be edward scissorhands and id be alright with it. Reading stuff people post publicly isn't creepy, or liking peoples pictures to me - it's when you find out stuff people don't post and tell them those things that is creepy imo lol.

When a person comes onto you really hard. for example: When you know that person for only 1-2 weeks, and they tell you "I feel like you can make my life feel more comfortable." To me I'm going like its been 1-2 weeks and I feel like your trying WAAAYYY to hard to get closer to me.

That is true, but then you are in the awkward situation of (Man...I don't know how to tell her she is coming on to fast...) and have no clue what to say next, cause if you just say "Oh thanks." then you will make the situation awkard as well right?
