I hate my friend and refuse to help her because she's been lying to me and having sex with someone else's husband
In what ways has your friend been lying to you?
She's been lying to me about many things, I'm tired of her excuses.
If your friend has been chronically lying to you, it's understandable to feel upset. However, you should not disregard their need for help if it is indeed a sincere need. You should help your friend as well as talk with her about how her lying has impacted your trust and that it needs to stop.
It doesn't matter how many times I'll talk with her, she won't change and she's a big fat liar.
Your frustration is valid, but I believe it's best to take a breath and think more rationally. Don't you think your friend already feels a lot of guilt from the cheating and lying? Perhaps you two can take a day together and air out all your problems!
