How to get a Cancer male back?

Hi guys,
I'm new here. I've got a complex problem (aren't they all?) And I could use some advice.
I've been dating this guy who had been 'stalking' me through a mutual friend on Facebook. And by stalking, I mean, he always commented on the same status updates. And we'd have entire conversations on our friends profile. So I decided to add him after a few months, because our mutual friend was getting sick of us.
After a month of daily conversations on FB (private messaging) I asked to see him, because I was going to be in town for a concert. He agreed to see me and we had a wonderful time. A few weeks after that I asked him out again and we had a picknick, he cooked for me and I had made him some applepie. We had fun!
So after that date, a week or so after, I asked him out again. It took him 3 days to let me know that he thought it was too much to see me 3 times a month but he would still like to see me in the future. So, being the taurus I am, I took this warning a little too seriously and didn't ask him out. Until after 2 months he suggested we'd spend Christmas together if his original plans didn't go though (visiting family abroad). I told him this was fine, under one condition; that I'd see him before Christmas.
So we went on a wonderful date again, we went to a gallery and had a nice dinner. He told me the next day he had a wonderful time.
Mind you, inbetween our dates we were in touch every day, sending eachother messages.
His family plans for Christmas did go through, and he promised me he'd bring some gifts for me, the next time he would see me. Which would be after New Year. He suggested we'd meet on the 14th of January but I really wanted to see him, so I was kind of pushy, which he didn't like. The next day I apologised, told him I wouldn't act this way if I didn't like him.
The 2 weeks go by and things were going well up until the day before the date.
I had suggested a movie to him from our favourite graphic novelist. I had not specifically asked him to the movie, but did hint I had a surprise for him, relating to the movie (it was the graphic novel of the movie, and I wanted to take him to the movie). He then messaged me telling me he loved the trailer, that it moved him so, that he had tears in his eyes. I then said, well I'll have a nice surprise for you this Saturday! And then he said he had a surprise for me too.
Two days later, he posts the trailer of the movie on his wall and tags his friends, and ask them to the movie!

But a week earlier he called me clingy and dependent. (which I can assure, I am not) and when I confronted him he referred to clingy and dependent. Which made me even madder. So I confronted him. He then replied that he could go another time with me (logical explanation..)
I was still cooling off and received another message from him saying he was mad that I distrusted him, and why didn't I just ask him to the movie? He then explained that he hadn't seen his friends in a long time, and why shouldn't he go with them? He then said I shouldn't contact him he would contact me.

A week goes by, I didn't hear anything. I then asked him if he was still mad and said he was tired of my paranoia and possesiveness. I got mad once more and told him I'd make things easier for him and I defriended him.

Stuuuupid. Of course. But I did it. It's something I normally wouldn't do.

I sent him text messages a few days later explaining to him that I don't want this to end, that I adore him and that we need to work things out. No reaction. He then blocked me of Facebook.

Sent him a message 1 month asking him how he is. No response.

3 Months later I bump into him at a club. I first ignored him, he ignored me. But then I had a few drinks and stepped up to him. I held onto him, we had a nice talk about our lives. I then give him a hug and tell him that I miss him and ask him if he missed me. All of a sudden he backed away and said he didn't. That he doesn't have any feelings, that he has no soul (an inside joke). I got mad and told him I didn't believe him. I walked off, thinking I have to get over this guy NOW.
Next day I get home and I see he hasn't blocked me anymore. What is this?
I sent him a message and added him as a friend and he didn't respond. 19 days later I accidentaly sent him something because I was looking for some information in our previous conversations. I then told him to ignore that and said bye. He then blocks me once more.

What should I do? I know from experience that the people who had blocked me in the past wanted to get in touch with me (I know that sounds weird, but I can seriously give you 2 examples, haha)

I've decided to call him, but I do not know how to approach him. Can you give me tips?

Thank you in advance and sorry for the long story!
