Wth happened with this Cancer man?! HELP!

Please everyone, I'm here to get some straightforward/honest advice on this mess that I put myself into and not to be bashed.
Wish I could make this long story short, lol...
I've been friends with a Cancer man for over 13 years. I'm an Aquarius. We both admitted at the beginning of 2013 that we were really interested in each other (like being in a relationship interested...getting to know each other better). Yeah, it took us that long to admit it. He did admit that he was in a relationship of convenience. He knew I was also involved with someone as well (on the verge of breaking up). Anyways, we went out on a few dates and have been intimate for the past almost 1 year (crazy nights of passionate love-making, dinner dates, etc.). Anytime I wanted to see him, he'd always come around with no problems and vice versa. Just a few weeks ago, he has become very distant with me when I ask to see him. We would set a time and date to hang out but then he'll just be a no-show without excuse (very rude and disrespectful). It's bothering me that he's been acting this way. It's ok if he's lost interest in me but I figured that with our long history of friendship he would just keep it real and tell me instead of leaving me out in the cold as to what went wrong. Also, I gave him my laptop to fix over the summer and he never gave it back, giving me various excuses for not returning it to me. The last excuse was that someone stole it, which I know is a lie. The last conversation we had was a week ago (through text...he won't answer my calls but will answer my texts...I guess because he's trying to avoid confrontation) when he got mad at me because I called him out on how I've noticed his change of attitude towards me. I told him that he could've just gave me the respect as the friend I thought he was and told me that he was no longer interested and we could've been done with each other on an intimate level. He responded by telling me that he would "mail" me another laptop and not to text him anymore. But the next day, he said we were still friends and that friends have disagreements. I know I'm far from perfect and I should've never crossed that friend zone with him but damn, our friendship could've ended amicably. I've made up my mind to not contact him anymore because I don't think friends treat friends like he's treating me.
My questions are: Should I take him to small claims court to get compensated for my laptop or just forget the laptop and leave h

CluelessCancer- I have created a paer trail which will help to prove my case if I were to take him to court. I've asked him about the laptop plenty of times throughout those 6 months and he just gave me nothing but excuses! I have ALL the text messages to prove it! Forget about being d-----! I've even told him that I would take him to court a couple of times during the 6 months. He must've thought I was joking because we were still sleeping together. It's not about revenge or being angry...

I meant to say "paper trail" not paer trail...

Yeah, you're right CluelessCancer. I'm gonna do just that.
But can you give me any insight as to why he just did a complete 360 on me? I'm kinda hurt and lost as to why he would do such a thing when we've been friend for so long. And do you think he will reappear?

Ok

Miha- Thanx for your input. That's why I wrote my story here, so that I could get different opinions. I understand where you're coming from about my suing him being out of revenge but I don't see it that way. As I've stated earlier, I discussed taking him to court while we were dating. So he knew what it was. And I never said that I wanted to befriend him again. I said our friendship was done. I'll never feel the same about him...ever.

Stop with the immature horseshit already! He's mailing you a lap top. Suck it up, grow up and move the fuck on.

Thanx for your input LetItB.
