My ex trying to kiss me – What should I do next?

Long story short I haven’t contacted my ex in over two months or so nor have I actively tried getting him back. Some of his actions seem to have confused me though. How would you understand the following? (they are in order) :

– Looking rather stricken and emotional when seeing me – Adding me back on facebook – Lying deliberately to my friends that he has a girlfriend then asking my friends to say ‘hi’ to me for him – Looking panicked and stricken when he sees a friend I’m closely associated with – Liking some photos, poking me, on Facebook – Now, over a week ago my friend lost me around town, saw him and asked him for my number. He gave her the number than insisted very seriously on talking to me himself. My friend who was with my at the time answered the call and refused him talking to me as I was in no fit state to speak to him. But he didn’t know that.

How would you read his actions?

Also, last week he saw me kissing another guy (It was not deliberate to make him jealous, just bad timing) and did not look really happy and pointedly started avoiding me when I walked over to his group of his friends, yet one of his friends did ask me to join them. Did this kill my chance of ever getting him back?

I’m 17. he’s 19. It was a rough break up, he basically lost interest in me due to believing a rumour about me cheating on him. He would not believe no matter how much I tried convincing him it isn’t true. I was very expressive with him about my feelings for him and tried my very best to rekindle things and show him I’d never do such a thing.

Just yesterday, he came in the same club I was in, trying to touch me, cupping my face and trying to grab my attention in general, He tried to strike a conversation with my friend and I. I kept things short and polite yet then he leaned in to kiss me and I walked off. I’m scared that after this, he might really get the idea that I don’t want him in my life or that he’ll never try to contact me. What should I do?

thanks
