<human>: Can you give me the gist of the text in a nutshell?

I feel disrespected by my friend and feel like he used me. Details aren't important, but I'm really, really hurt. 

I want to confront him but I don't know how to go about it. I'm extremely pissed and just want to yell at him, but I don't think that's going to help at all. 

Right now we have been ignoring each other for weeks, so I feel a little awkward about calling him. How do I approach it? How do I confront him (over phone or in person?) and what do I say? I'm freaking out a little as you can tell, but I'm not a confrontational person so I'd like some advice.
<bot>: How do I tell my friend that I feel used and disrespected? We haven't talked for weeks so I wouldn't know what to say if I called him.
