Ironically, I simply googled "delayed emotional response" found Marlene's posting, prior to this - I had recently been Diagnosed with PTSD. Low and belhold I found this wonderful website - Thanks Marlene

I have typically been a stuffer most of my life until things caught up with me about 4-5 years ago. It became very evident while I was in a relationship with a fairly problematic person. I noticed that when he would do or say certain things, I would feel like something "was not right" but that was all. Often it would take several days for me to figure why "it" did not feel right and by then - a lot of water already under the bridge, many times I would just discard it or he would have already started up new drama for distraction. In some cases though, I did bring it up (sometimes weeks later) - but it really was not "in the moment and less effective. Imagine being in a relationship with someone that responds to things much later...? I was worried about my ability to have a meanful connection with somebody.
One thing that helped me? I mentioned this to a friend of mine (also in therapy) and she gave me this Tip - she said. "It's important you start somewhere. Next time he says or does something that does not feel right - say it, tell him!" I replied "What?, just say...that does not feel right?"
She said "yes!"... I said.."but then he will ask what, why, how and I won't be able to explain - I'll sound crazy"
She said, "no, Simply say.. "That does not feel right, or what you said does not feel right" If he asks more, simply say, " I don't know, it just does not feel right. Not sure why, let me think about it and when I know why I will tell you"
Please know that this tip did not fix anything or stop my delayed emotional reactions. But it did help me to make some attempts with connecting/communicating with another person I care for and additionally validate that I DO have some response
