My boyfriend lies to make me happy?

[:)]

When we started dating he said he had nothing on the day I was free so we could go out, but he had an important football practise which he missed

Then we went to see a film, and he said he hadnt seen it before and really wanted to see it, but now ive found out that he had actually seen it before!

Another thing, I was joking about this woman in a bikini on TV, and he said he didnt notice her because he doesnt look at other women. I said 'oh sure you dont, its ok you are a guy its normal to look at other women' and he insisted he doesnt. BUT ive seen on his facebook and twitter he keeps adding and following random attractive girls who upload semi nude pictures. I would be fine with this if he would admit it but he wont admit it!


I find it sweet that he wants to keep me happy, I am his first girlfriend and we dont want to lose eachother. But I keep feeling fooled and tricked and i wonder what else he has lied about. What should i do? How do i get him to be more honest?

Thanks for your advice xxx
I would tell him, but i only found out about some of the stuff by looking at his twitter page and facebook page... so im worried he will get angry for snooping on him (i know its my fault)
Also what if he denies it again...?
What should i say when i tell him?

'Hey, i think we should be more honest with eachother, starting with how its ok for you to look at women so dont pretend that you dont'
