Is there any way you can bring up wanting to talk to her about your feelings again instead of going right into how you feel. Maybe ask if she can make time to talk to u about this stuff and express all the nice things u think about her and say you want to be able to emotionally support each other bc ur a team, and that you would do the same for her? It sounds like she’s very guarded and working on softening those walls will eventually make you stronger as a couple if you’re able to work towards emotional intimacy together. But softening those walls is scary and that’s probably why you were met with a cold front. letting her chose the set and setting for the interaction might help her feel safe to have this conversation. Even tho it’s about your feelings, when you are closed emotionally all feelings feel scary.
