Relationship advice... What should I do here?

Ok, so we met in December and made it official in Jan.. Everything was going really well, we both said we where really happy and couldn't believe how well it was going etc.

Anyway, last week we had our first proper fight over something really stupid and didn't speak for a day, he then ended it.

We met up the day after and had a long chat, both said all the things we wasn't happy about etc and he said the main reason he ended it was because he had been talking to other guys online (only as friends and most of them are in diff countries) but he felt guilty about it because my last relationship sort of ended because my ex got talking to someone then ran off with him.

Anyway, we then said instead of rushing back into it we would go back to dating and see how it goes. Yet since this he doesn't seem to actually want to see me or talk very much and when I have seen him, we don't cuddle or kiss or anything anymore. I tried to ask what was actually going on with us and he got all stroppy and said just go with the flow.

Then last night I asked if he wanted to do something but he said no, he wanted a lazy night so I went to see my friend.. while out I text him saying I wanted a hug and kiss, his reply was get your friend to give you one and was being really distant. I stopped texting him then got a text saying 'I'm watching a film, wish you where here with me' I ignored that one too and then got one saying 'I'm thinking about you' to wish I also ignored to then get one saying 'Sleep well tonight'

Anyway, I text back this morning just saying hope ur ok etc and not really spoke much today but then he just called and invites me round his tonight and invites me to go to his friends wedding with him..

I'm so confused as to what is going on here but can't seem to ask without him getting stroppy :S Any advice would be muchly appreciated!
