Hey L, yes you are correct. At this point she would most likely not be receptive to affection. You’re sitch is very early on and right now you need to give time and space. She needs to see you aren’t available to her, especially if AP is involved. Every sitch is different and what works for some people may not work for others. Make sure to 180 on all other negative behaviors but 180ing on the affection may not be best at this time.
In my sitch I went NC for about 3 months besides child care discussion. This time was very important as it gave us both space to see what life was without each other. When she started reaching out to me to work on the R is when I started showing affection again.
This is a very slow process and it could be many months or years before things improve. No rush though, stay the course.
