For the most part good job with the story. The only down side that I have with the story is the Buffy being mad at Willow for pushing her towards Angel, to keep her away from Xander idea. Which makes absolutely no sense. For one thing it was actually Willow that suggested to Xander that he ask Buffy out, before they knew how in love with Angel, Buffy already was.
However, the worst part in this chapter was you comparing Willow not trusting Buffy to her parents putting her in the insane asylum and her friends at Hemry turning their backs on her after she became the Slayer. This just kinda pissed me off. You're comparing the trust between two people that have known each other for less than 6 months, to the trust between a parent and their child that they raised for 15 years, or the trust between friends that have known each other for several years. And you're saying that the "broken" trust between two people that have known each other less than 6 months is worse than "broken" trust between the other two. I'm sorry but that opinion is just f'ed up. Especially when the actions that you're basing it on is contradicted by the show your story is based on. I mean heck after finding out Angel was a vampire, it was Willow that was pointing out the negatives to Buffy about a relationship between the two, and Buffy didn't care. So I'm sorry but that idea that Willow pushed them together makes no sense.
Edit: I never said that Willow was anti-Angel. I did say that she pointed out some of the problems with Buffy being with Angel. And remember in that episode in the second quote that you picked out it was Buffy that changed the topic to talking about Angel, Willow was trying to help her study math, and after the bit you picked out Buffy thanked Willow for pointing out the negatives of being with Angel. Also in episode three it was Willow that encouraged Xander to ask Buffy out after he gave Buffy the bracelet, hardly the reaction of someone actively trying to keep them apart. You're quotes are pretty much examples of a girl talking with her first girlfriend trying to support what her new friend wants. Buffy was enthralled with Angel from the very first, before Willow and Xander had even met Angel, Buffy was already looking at him in a romantic romance way. You have to remember that Buffy is Willow's first real girlfriend, the last thing she's going to want to do is do anything that might ruin it, and when Buffy is making it pretty bluntly clear that she wants a relationship with Angel, she's not going to be openly antagonistic to that relationship.
For your view of that attitude it should be Willow bringing up Angel and not saying anything potentially negative about the relationship. But its Buffy that's the one that's bringing him up, and even then Willow does point out potential problems with the relationship, such as his living forever, and the lack of children. It's true she's not as openly antagonistic towards Angel as Xander is, but not being openly antagonistic is different that pushing Buffy and Angel together.
In regards to the other part. A friend that you made 5 months ago, not trusting you shouldn't be worse than your parents turning against you and throwing in a psyche ward after 15-16 years.
Willow's comments after finding out Angel is a vampire:
Giles: (sits and looks through the diary) Angelus leaves Ireland, uh,
wreaks havoc in, in Europe for, uh, several decades, and then, um, about
eighty years ago, the most curious thing happens. He, he comes to, uh,
to America, um, shuns other vampires, and, and lives alone. There's,
there's no, no record of him hunting here.
Willow: So he *is* a good vampire! I mean, on a scale of one to ten,
ten being someone who's killing and maiming every night, and one being
someone who's... not.
Willow: Okay, so here's something I gotta know. When Angel kissed
you... I mean before he turned into... how was it?
Buffy: (smiles) Unbelievable!
Willow: Wow! And it is kinda novel how he'll stay young and handsome
forever, although you'll still get wrinkly and die, and... Oh, and what
about the children? (Buffy looks at her) I'll be quiet now.
Buffy: No, it's okay. I need to hear this. I need to get over him so I
Willow: So that you can... (makes a stabbing gesture)
Buffy: Like Xander said, I'm the Slayer, and he's a... vampire. God, I
can't! He's never done anything to hurt me... (collects herself) Okay,
no, I need to stop thinking about this. Okay, let's give another half an
hour and maybe something will sink in. And then I'm going home for some
Buffy: No? I invited him into my home. Even after I knew who he was,
what he was, and I didn't do anything about it... 'cause I had feelings
for him, because I cared about him.
Willow: If you care about somebody you care about them. You can't
change that by...
Buffy: ...killing them? Maybe not. But I think it's a start. (starts to
Willow: So, no word from Angel?
Buffy: Nah. It's weird, though. In his way I feel like he's still
Willow: Well, in a way he sort of is. In the way of that he's right
Buffy looks over where Willow is looking and sees Angel. She briefly
looks back at Willow and then heads over to him.
Xander: I don't need to watch because I'm not threatened. Just gonna
look this way.

Where in those quotes from the show do you get that Willow is anti-Angel? Xander did point out negatives but Willow doesn't seem to have based on the above.
Also, I never said Willow pushed them together but rather encouraged Buffy with anyone but Xander.
As for the time factor you put forth, some relationships can progress faster than others so it is a toss up as to how things will affect a situation. My scenario is no less plausable than someone elses'.
I do appreciate you expressing your views but like the heads of state or companies, advice may be listened to but doesn't have to be followed when making the final decision.
