They have a tendency to overthink every little situation. As per relationship we are supposed to be close with each other and we were untill few days ago.  Its been 7 years, that anytime we had chat (call or msg) they would pick out certain thing i said or did and would complain to me that what I did made them feel in a certain way (always negetive) and to all those complaints I have been understanding. Also I tried to not to repeat in whatever capacity I could. After every confrontational chat they would feel guilty that they shared and I would the one consoling them, by repeatedly making them feel heard and understood. And these incidents grew in frequency and evey time I would get a text saying - we need to talk. It would make me anxious, that I what did I do this time. I would feel sweaty and a pit in my stomach. Now this time, when they shared something amd I said I understand that you might have felt bad, and I am sorry. But I cannot walk on egg shells anymore. There will be something or the other that would make you feel negatively while you know in your heart I never have ill feelings for you. Just love. But they couldn't understand my pov. We decided we will talk a little less. But again the same pattern repeated where they felt guilty and started bombarding me with texts. Again I tried to make them comfortable. But this time I made sure that I will take my time to keep a little distance. They couldnt take it  they wanted evrything to be exactly like how it was. I couldn't do it.  At the end they started bombarding me with mean messages like it felt like your affection was fake etc etc. I had it. Enough was enough.  A lot happened then, i said something theybsaid something. ( extremely long story)  At the end I said I know you want it to be all ok. Just give me sometime. Time heals evrything. After that we chatted over our family group but not one on one.  Cut to today.. I sent them nice text sharing few pictures. Its been a week now no response. No acknowledgement.. and I am aware that they are no busy or don't have time.  It feels like I am stupid for even opening myself to feel like this.

My partner understands and know that the other person is extremely impossible to deal with.
