<human>: Could you distill the essence of the text into 1-3 sentences?

Hello reddit,

I was in a relationship with her for ~5 months though it did go on and off a little bit due to obvious issues between us. 

Well, I decided to end it because I don't believe we have that much in common, I don't really feel that much (though she's a good person and I like her for that) and lastly, truth is, I may not be ready for a relationship since I came to figure out that I felt kind of trapt and not able to focus on my own things which turns out I need to do more right now (pretty selfish).

So, I told her the last thing of all those because she kept pressuring me for a reason that I don't want to be with her. 

She also acted like we were still together while we were not so I had to remind her etc (in a nice way but obviously I didn't like doing it). 

I told her I wouldn't be good in the relationship she said she didn't care and so I said I just don't want a relationship and that that's how I feel.

So, she reasonably got angry and said some really bad things ( "fuck off" and "I hope you find someone that is equally emotionless/insensitive as you" and to go to hell).

 Now, I know I probably deserve all that but I just want to know if I should've told her those other things too, would that possibly had helped her more in the long run (in order to deal with the break-up) or not? 

I just wanted to make it as less painful as possible but maybe that was wrong. 

So, I am asking for your advice on the matter, if you have any that is.
Thanks in advance.

P.S: I hope this post belongs here I was not exactly sure about it.
<bot>: I only told one reason of why I broke up with her when she asked and now I don't know if I should've said it all"
