I feel really bad. I need some good advice?

Tonight my boyfriend, my son and I went to our friends house to watch the game. Well our friends brother happened to be there which is no big deal because he always goes over there with his wife on game nights, but his wife didnt go this night because she just had a baby, anyway so were there watching the game and it wasnt going the way we hoped ,so my boyfriend started to dose off. I looked over to him and saw him falling asleep and realized everyone else had left the room. The brother was staring at me which was weird because he barely even talks to me. So I looked away really quickly , and then looked back, and he was still starring at me. So I looked at him and he gave me that look. And if youre a girl you know what kind of look I talking about. I couldnt believe him. His wife just had a baby a week ago. What I feel bad about though is that I didnt tell my boyfriend. To me its not a big enough deal to tell him but Im not sure. I need some advice.I feel really bad. I need some good advice?
It is not something to be too alarmed over, but I think that you should at least mention it o your B.F in a manner that doesn't sound like you are making a big deal over it, so it doesn't cause a fued, %26amp; tell him that you may even have mistaken the look, but let him know that it made you feel uncomfortable. This way you hide nothing from him, %26amp; he now knows to be on a look out.I feel really bad. I need some good advice?
tell him be honest from the beginning because if something else happenes he's gonna think your responsible and wont trust because you didnt tell him the truth from the beginning... trust me this is a big mistake that people make and I've seen it end relationships left and right... honesty and trust are crucial to any relationship...
If it bothers you so much talking to your boyfriend might be a good idea, not to say you definately should but it might make you feel a little bit better. Whenever someone has made me feel uncomfortable by giving me that look i tell my boyfriend and he usually makes me feel better. So maybe telling him would be the best choice if you feel that uncomfortable but if you do tell him dontlet him confront the brother because he will only deny it.
Tell your boyfriend please, and make sure his wife know that too, it is better for everubody to know how he is. he is disgasting.
I wouldn't mention ';the look'; to him right now. Now, if his brother actually tried to make a move on you, you need to let him know that it is never going to happen. If you go to your boyfriend about it, then you are putting brothers against each other, and it is never a good idea to be the one in the middle of a family squabble. In the end, family will always choose each other.
