she's mad at me but won't tell me why!!

Why don't you try to talk to her seriously. Otherwise, she must be wanted to give more time to think about what's going on to her.

I assume that you guys don't live with them or near them, right? If that's the case and despite your attempts to be friends with her or even to get her to talk what's up, then just be civil and polite with her whenever she's around and then forget about it. If you know that you have done nothing wrong then let her be. Some people just can't help being upset with someone for reasons they themselves only know. Don't let her attitude dampen or prevent you from having fun with the rest of your family, and don't let her stand in the way of you ahving a good relationship with your brother in law and their kids. It is a matter between you and her, and it doesn't extend to the rest of the family. Just be always open to the possibility that once she's ready to talk, she will approach you about it. You have done your part, now the rest is up to her.

She doesn't want to talk the matter simply because she know it was her fault. So- If I am in your shoe- I would rather forget everything and just like what she wrote- start all over again and forget what happened. At least you know your conscience is clear- let her feel the guilt feelings.

That was weird! Why wouldn't she tell you about it? Maybe just let it pass now then ask her what happened in a few weeks. At least you can defend yourself if there was something you did that offended her, even if you are okay now.

Sorry to hear that she is offended and you don't know why. Obviously she feels you said something that offended her. Perhaps it is better to let it go and just move on. To bad she will not let you know what you did so that you will not make the mistake of repeating it. It's hard to fix something when you don't know why something is broken.

Something in our life is very strangely,if we don't face it,maybe we can't find our happy life.I think you will defuse the unpleasant rely on your kind-hearted.

Maybe you should ask the other family members because that would mean they probably know something after what she said " for the sake of the family " . It is hard to move on and you dont know what you did in the first place , what if you offend her again?

If she is really that piss off at you, it is better off for you to forget about talking with her anymore, until she change her mind, you should move on and let her has her way, it is fine if you have no idea what the heck is going on, it is not important now, just forget about her for the time being.

I think if you both said hurtful things you are willing to work things out and she's not so she's wrong. You try what you can, ask once and if she continues with this it just mean you meant nothing and don't loose your good efforsts on her.
