Well honey I feel for you inlaws can be a real pain unfortunately. Even more unfortunately, I don't think there is a real cure all. I mean she obviously has a deeply rooted resentment towards you and I don't know why, if you think about it really hard you may be able to realize something though. Could be though, that she is just jelous of you. I mean especially if your husband and him are close or maybe went through something heavy together, things of that nature. You know until she realizes her own issues she won't change. Anything you say will just make things worse because she doesn't want to get along with you she will not!! You're just going to have to learn how to 'handle' her. I use this term loosely. I truely mean 'manipulate'. You're just gonna have to learn to predict what her response to anything you say or do will be. Don't say anything she can twist just always be extremely general with her. Always be polite, smile through your gritted teeth haha You know, just be very adult and mature and if she looses it and starts acting like a real witch be as nice as possible and just kind of look at her and everyone like what the heck is wrong with this chick. The more you don't react to her the more you keep your cool the more she will lose hers. If you are the calm cool assertive one she has no choice but to play the other role so to speak, because she wants to. You come out on top looking like the bigger person. I just want to make sure you understand that I don't mean kiss her back side I just mean maintain yourself. Stay composed and just learn to be very agreeable while in her company. Don't let her cause fights between you and her husband. Don't let her get you all frazzled YOU decide what YOU feel not her!!!
