l think you should talk to your girlfriend, not your friend. She might like the way your friend treats her. Perhaps that's why he does it. Why don't you tell her to ask him to stop? Malcolm

If I were you, I wouldn't say anything to your friend. I think you should lock your clothes in a cupboard. You'll soon get the message, and that way you'll stay friends. Maria


You shouldn't be so sensitive. It's not really a problem, it just shows your friend thinks you have good taste. And don't argue with your friend. Women aren't worth it. Darren

I think it depends if your friend is good company or not. If he is then I think you should pay for him. If not, don't tell him where you're going when you go out. Silvi


When your friend gets home tonight I think you should talk to her. Say"I'm really sorry but Im a bit obsessive about my things. I don't like other people touching them." That way she'll stop but she won't get angry or offended. Sandy

You definitely shouldn't pay for him. When the waiter brings the bill, pretend that nobody has money to pay for him. Then he'll have to make an excuse to the waiter and maybe he'll learn that he has to pay for himself. Martyn
