Mixed signals from ex.

I'm not really sure what I'm asking for or anything. Sorry if its long.

But last night, I went out for drinks with a mate and quite a few people were there, and was all really social and I had a really good time. Thing is, my ex was there. I hadn't seen him for quite a while. He has a new girlfriend now. I have seen him out a few times, and given him the heads up, and we just acknowledge eachother and then move on. I have even seen him out with his girlfriend, who actually hates me. (Background info: this girl was his girlfriend before me. He broke up with her for me, and then finished with me to go back to her. Clean break up, not messy etc).

Anyway, yeah. She gets really funny about him and me. And I think he tries to keep communication between me and him to a minimum when he is out with his girlfriend. For obvious reasons; she is very paranoid.

But yeah. I went out for drinks and my ex was there. We got on really well. It seems like we get on much better when his girlfriend isn't there. But after I went home, I got a text from him saying 'Good to see you tonight etc' and then we had a big text conversation. But the thing is, he kept saying things like 'I just want a really big hug right now' and 'Spooning is what I need right now, and if I could, I would spoon you now.' He also highlighted the fact that he was just in his boxers, and wanted a hug :/
It was obviously in a light-hearted manner, well at least that is what I thought, and that I am not really reading too much into it.

I was just curious, would this be considered 'normal' behaviour from an ex-bf who is in a relationship with another girl? I'm not sure if he wanted to get a reaction from me or anything, I was just a bit like 'Okay, thats a tad weird to hear :|'

Anyone else experienced something similar?
