Am i obsessive or is this normal?

I started seeing this guy last Autumn, it started off pretty intense.. Was very quick to develop into supposed 'love'. We even spoke about marriage and kids and moving in together. I was blown away by it all. He even told me time and time again that he wanted to be with me at xmas and visit his family in Greece. So we booked tickets together.

Things started to turn sour about a month and a half later, he worked nights, i would be at home wondering where he was and what he was doing and started to feel very alone Our schedules clashed and there was the added issue of his ex-girlfriend constantly texting , which he always entertained to my distaste.

We had our first tiff one Sunday, I was so emotional, as his ex was calling him in the middle of the night and texts blah blah ' i hate you , you are a liar' i screamed at him. He didnt deal with it well (and looking back im not sure if anyone would but it wasnt fair on me)

Ever since that arguement, things never felt right, it was as if he was unhappy but not dealing with issues. He never liked to talk or discuss anything emotional. It was just banal.. I was unhappy and I knew that deep down, perhaps I was just clinging on to what we had a first.

Towards the end of November I checked my his facebook status and it was all doom and gloom so i text him asking what was wrong. He replied saying that he didnt want to be with me anymore. I was pretty upset, pretty cut up as he never told me what was really wrong.

A week laterI went to the place where he works, I wanted to ask him what was going on to his face. When we eventually got together to talk he was bright red and would not look me in the eye. But we got back together adn he told me he still loved me!

We arrived in greece i was dead excited, I tried to make an efford iwth his mother and step father and looked after him when he was ill. He seemed really down, and unhappy and began to withdraw, constandly texting on his mobile phone and not talking to me very much.

On the night before nye He said ' i dont think we should be together anymore, im really sorry i cant lie to you'

I burst into tears and had a major panic attack, i felt really helpless in his mothers house in greece the night before new years being dumped.

The next day I still cry then his mother bursts in and shouts at me 'why, why are you crying?' then he comes in the room and she says ' you should stop crying, if he doesnt 100% love you thats not his fault, its new year get over it'

In the evening after his parents had left for a party , we just sat in the living room .. I just kept crying, he was there in silence texting on his phone. It was horrible. ' I want to go home' I said.. I didnt want to be there with him in that house. I wanted to go back to england..

I never get to speak to him again after that, even in the morning he didnt talk to me.

A month later he is with another girl, I am jelous and obsessing over it.. Is this normal?
