I Hate Fake People

So I became friends with someone at my school early last year. We became so close, almost like brothers. I got really attached to him and his two sisters and his mother. We were almost inseparable, catching the bus together and having sleep-overs at his house. We even fooled around quite a lot. But eventually all of his lies just started falling apart. He lied about so many things, it's unreal. Most of it, there was no use lying about it in the first place! He isn't the person I thought he was. We're not talking any more. If he messages me I'll talk to him like normal, but that doesn't mean anything's changed.
