My sister boyfriend is flirting with me?

If you think she will take his word n wont believe you, then try to record his voice when he is on phone n talkin to you or replace a camera in ur house n invite him to ur house then he will show his real face n u will have a strong clue in your hand to show ur sister!

You shoul help her n save her from thiis pi*p!

Think of it this way. Would you want to know if you were living with a lying, two-bit cheater? And would you be angry if your sister knew and didn't tell you?

I have a sister I am very close to. She is my best friend. We had this conversation one day. I told her if a boyfriend of hers ever came on to me I would instantly go and tell her. She was surprised by this and asked me why. I told her because she deserved to be with someone who would love her and not cheat on her and I would consider it my duty to be honest with her if I knew the truth of how her boyfriend truly was. I told her she should do the same for me.

So, what you do is, get them both together, sit them down, and tell her what he has been doing. It will be hard for him to deny it if you are sitting there and laying it all out to her. It will hurt her, but it would hurt her more to one day find out he is a dog, you knew, and didn't say anything.

Your sis deserves better than this creep. I hope you do the right thing. It will hurt her for awhile, but she will always know that no matter what it is, or how hard it is, she will be able to depend on you. And what better gift can one give a sister than that?

Now, if she chooses not to believe you and fall for his line, whatever it may be, you will at least know you tried to be honest with her. What she does with the information is up to her, but I bet she believes you.

Best wishes

I think you should tell your sister otherwise he is just going to come between you two. Guys come and go and you can't replace a sister/brother. Go to her open and honest and let her know everything that he has ever said or done to you behind her back. Expose him for the true jerk he is and she may be hurt but at least you have stopped him from hurting her any further than what he has already done.

Of course you should tell but make sure you have evidence(record the conversation,if you must) of his bad behavior. Invite them over and have a sit down with them both about this situation... this should have been dealt with the first time it happened!

Your sister needs to get in counselling so she can learn how to cope with break ups.... (go with her for moral support).

Should you tell her, should you tell her. That is your sister rule number one is never talk too your sisters boyfriend and if you do then you are a slut, you did need to come on here and ask our opinion you should have already known that answer,dont be stupid tell your sister that her bf is a creep.

Just tell her kindly, "I promise you I'm not lying, but your boyfriend has been hitting on me when you're not around. I understand if you don't believe me, but I thought I should let you know what he's been up to. Please don't let this affect our relationship in any way." If she doesn't believe you now, she can't say you didn't warn her.

girl let me tell you blood is thicker than water. Tell your sister as soon as possible she don't need to be with a creep like that.

beat the living daylights out of the guy and be like hey lil beotch your goin out with my sister and i would never do something like that to her. so never talk to me agian sick freak!

about the part that ushould tell her i cant help u on that. srry.

You need to tell her. She will get hurt worse if you dont tell her right away.

u gotta think long and carefully about this. u dnt want ur sis find out herself that wud probably make her worse.
