(31M) and (30F) have been engaged for the past year and our wedding date is in the next four weeks. The planning has been very stressful on my to be wife and I haven't known how to really help her. She keeps telling me that she feels alone and is getting help from no one. However, I have made myself available regularly and when I ask for what we need to complete for the wedding I am met with yelling and her telling me that she has told me what needs to be done. Which I do not recall actionable things she has shared. If she has given me actionable things, I've handled them swiftly. Essentially, our communication is failing greatly because I don't know how to help. With this communication problem I tried to contact outside parties including a wedding planner to help take some stress off. Idea was that the communication between them would be more constructive than what we are currently dealing with. She will not respond to them and tells me I am pushing her off on to others. I am really just trying everything to help.
We have pretty much everything planned and in place yet she is still overly stressed and not opening up with how I can help. I have been going above and beyond taking care of housework, cooking, and trying to allow her to take it easy. I've given up a lot of the things that keep me away from home so I can be available and try to spend time with her. This is not met with gratitude and she doesn't appear to notice the effort I am putting forward. She doesn't seem to have the energy or want to do anything besides decompress on her phone. I feel really lost here and am not sure what I can do.
Has anyone dealt with this in their relationship? What did you do to cut through the communication issues or what would you advise?
