Your son may feel torn between the two of you and this may be why he is trying to bridge the gap in communication. His wife may be threatened by you that you are the most important woman in your son's life and this is why she tries to put a wedge between the two of you. Although he is your son once he married his wife he put all of his energy into his marriage as he should do. Try sitting down with them both and talking things out and explain to them both that you feel there has been alot of miscommunication on both parts if you go into it only blaming her or them it will only get worse. Since they plan to move back to the area maybe that can be a stepping stone for you and your daughter in law to spend some time together and kind of start all over.
She may have it in her head that you just don't like her because she took your son from you show her that the two of you can co exist, it is good to listen and sometimes not respond just listen without giving your opinion in matters that involve a decision about their marriage. Do what you think is best, XXXXX XXXXX turns out you were wrong, admit your mistake. Most of the time, especially if they are married, you might unintentionally involve yourself in their marriage and your son may use what you say to him against his wife to get the upper hand in private matters especially if he tells you about how they aren't getting along with their mate. If you don't want something to come back and bite you later, don't involve yourself in their private family affairs. Respect that they are a couple and you raised your son and he is an adult now and it's his marriage and allow him to learn through trial and error.
There is a respectful way that you talk with your daughter in-law that doesn't makes her feel like you are rejecting her, or that would make her rebel against you. Make her feel appreciated for her actions first, then state your feelings. She will be more willing to listen if she sees that you actually care what she thinks and how she feels. If she says something that you do not agree with take a mental note and then let her finish and then talk about what you disagree with she will be more willing to hear what you have to say if she feels you have showed her the same respect. You do not want to continue to be at odds with her and then when she has children (Your grandchildren) she won't want you around them because she will think you are going to influence them in a negative way against her.
