Is AUTHOR wrong in the post ? POST : To fully understand whats going on I will summarize the background of this whole situation with timestamps.  
English is not my first language and I am fucking confused ATM so please excuse any spelling or grammatical errors.   
TLDR at the bottom.

  


In february 2018 I (M23)  had FWB-relation with a girl (F21), lets call her Kim.

The whole thing lasted until march.

In april 2018 I came back together with my current GF (F22), gonna call her Jess. 

In november 2018 I was told by some distant friends from my area that Kim is pregnant and is due the very next day after I was told she was pregnant. So I had no clue at all that there was the possibilty, that I was going to become a father.  
A paterity test prooved that I was the father of the newborn girl. During this period my GF has been highly supportive.

Short-Cut to today.

Jess is not handling it very well any more. My life became a constant balancing act beetween work, studies, Jess and trying to be a somewhat father figure for the child. I always try to involve Jess as much as I can in everything regarding the child. I even send her screenshots of every message so she doesn't feel left out or that there are things happening behind her back. I truly love my GF and I hate that I have put her in that kind of situation.   
So as of today I tried to make an appointment at the bank to set up an account for my daughter where all money like child support go on to. In order to do that Kim has to go to the bank with me. I reached out to her to make an appointment but she canceled via text message because her grandmother has passed away.   
From here on everything went downwards. I expressed my sincere condolences and told her that I will rearrange the whole thing. As usual Jess gets screenshots of this whole scenario.   
I didn't expect a response to that at all but Jess suddenly lost her composure. She told me that it pisses her off that I expressed my "sincere" condolences and not only "my condolonces". From there on it all spiraled down. She told my to not be so gentle towards her and that she wishes us good luck with our little family. There are much more things she said but honestly I am not in the mood to write it all down. Of all things that were said, the thing with the condolences annoys me the most because it makes me wonder if she is that emotionally cold and angry that she ignores the fact that Kim lost a beloved family member and pressuring me into treating Kim more badly. Jess even told me, that it feels like we are breaking up/drifting apart  at the moment. She then blocked me and since then I am sitting at work, not able to get my head around it.   
So am I the asshole for beeing friendly to the mother of my daugther who is a former FWB.  


**TL;DR: Expressed sincere condolences to the mother of my daughter after she lost her grandmother. Now my GF blocked me and accuses me of beeing too friendly and nice towards her.**
