Is he cheating? Advice needed!

I suppose all my suspicions started when a girl who he had never mentioned before got in contact with him and asked if he wanted to go out for a few drinks at a club in the next town down the highway. I was happy for him to meet his so called “friend” who he had known all those years, so I agreed and they went out! We were not living together at the time. I called him a few hours later to see if he was having a good time and the girl was shouting ar me down the phone telling me to f**k off and let him have a good night. He kept apologising and said she was drunk and that it was her first night out without supervision… Supervision?? Thats what I thought – he said she was mental is some way.

Anyway a few days later we were in bed and I wanted to look through his pictures as I took a few using his phone of a random event in town. And suddenly I came across some pictures of the girl in question naked and posing. I asked him about it and he said she must have sent them through blue-tooth when he went for a piddle (toilet). A few days later when he went for a nap – curiosity got a hold of me – and since 95% of my past relationships cheated on me, I wanted to make sure. What I found was astounding – she had sent them through text message and he encouraged her for them. And what made it worse was they were sent when he was with his and my mates who I thought I could trust. I confronted him – he closed up – eventually admitted it and said it was just for a laugh. Anyway – I let is slide by..it was just pictures.

Anyway – now and then he text her bitching about me whenever we had a fight of some-sort. And she would constantly flirt with him, called me a stalker etc;

He has locked his phone and laptop now so I can never get on.

But we still have problems which constantly make me think he is cheating. He never shows me affection unless I force it – he is always on his games – never talks to me! Whenever I try to talk to him about any problem – he closes up and says “If I don’t know what to say – I wont say anything at all” He is always on edge, panics when I go near his phone – try to distracts me when I want to go on his laptop, by suddenly becoming affectionate. And when we are out he is never near me or wants to be close – never kisses or cuddles – but when he talks to other people he is over the moon and smiles – when he is near me he is grumpy. He says he is not affectionate in public – which I don’t mind, but he isn’t affectionate when we are alone either.

He gets moody and ratty when I ask who has just text him or ask him about the girl from before. We hardly have sexual intercourse..maybe once ever 2 months if I’m lucky! (By the way – I’m 19 he is 26) The age does not matter to me or my family!

Iv’e suggested having a break for a while – but he said that its either we stay together or not at all. He turned down relationship help. Just sits on the couch all day plays his online games – eats drink and sleeps.

The other day he was sending long secret messages to one of his ex’s and when I asked about it he said they were private and just between him and her.
