How do I attract a nice guy who won't dump me for another girl? and how do I attract my best guy friend?

For your first issue, anyone who asks you to change in order for them to be happier is never a nice person. So you shouldn't even change one thing, let alone several things that make you who you are unless you decided that you need to change independently. I don't know your age but at a young age people get tired of the ones their with very quickly, consider a year to a year and a half pretty long because most people i know are in and out of relationships within five months or less.

Second issue, you need to flirt with him. Compliment him, push him, show him you want to be around him, and drop hints you like him. This is not flaunting, trust me, i love my best friend of six years and i am no way going to tell her my feelings unless she shows me signs that she likes me. I wish she would do these things every single day like she use to. For heavens sake, if he doesn't get the hint and your so positive it would work out great between you two just tell him. I didn't take the chance when i had it and i lost a chance to be with the one true girl i love because i was a coward! I found out she liked me too and i didn't see it. Do not let the moment pass when you think it's there, i regret my decision every single day of my life and the "what if's" are torture. For the record, when i am around her i refer to her as my "best friend" and she does the same to me and i have said she is like my sister before and she has said i was like a brother, and i love her so much more deep inside. Just because he says those things on the surface does not make them entirely true if he is trying to hide how he might really feel, like me and my best friend did to each other. Do not let something good pass out of fear to take a leap of faith. Trust me, if you don't make the jump it's going to suck, but the questions you will ask yourself if you don't try to jump will stay on your mind forever.

I would like to know better what happened with number one guy, maybe he wanted to cross the line?

Well, in that case you got the reason.

This new friend, i think is a classmate or a neighbor and that's why he treats you like that.

Sincerely i don't get at all people like this, boys dating female friends and vice versa like lovers do, and then pretend just to be friends, since the excuse is they know each other since childhood or there were no one else whom to get out. The only way possible to this kind of friendship without the ties of a courtship is to be the kind of persons who always are noisy and joking people. Those who talk about a horror movie and describe it comically to encourage others to go with him.

But, no matter how some people use their mood to keep a barrier avoiding courtships, this giggle ones are easy target for people who is seeking, specially for women. So if you fit into this description, I'd suggest you invite him to see a funny movie if you never did, maybe he is always the one who invites, the next time that you invite try for something romantic like a romantic comedy, avoid a noir film (cheating wives killing husbands with their lovers help thin) thing, stay away from movies like American Pie.

Look instead for something not rated R, something that is hilarious and good for romance at the same time and you'll see.

If movies is not your thing, a walk thorough a park could do the enchant, rowing a boat. Do at least three kind of different things lovers and spouses do, so he starts to familiarizing on his mind the idea of romance when he is near you.

If you don't dare to date, try to provoke the encounter walking where he usually does, and try to show a hobby you are doing at that place and never show yourself closed, and do it continually so the love begins to sprout.

That's it :-)
