Hi lianntu

Im sorry to read about your dad and you not speaking  with your partner. 

I see you reached out to him telling him about your dad's passing, and that he didnt reply. 

I can see you are very very hurt and angry about this,and I can understand that.  You've been trying to understand his action , by going round and round with all.kinds of scenarios as to what reason he could possibly have for not reaching back to you with some kind of love and sympathy  and understanding of what your actualy going through.

I cant tell you what to do ,but what I will say is maybe write a list of all the things you first came to love about your partner, even the little things how ever small or insignificant you might feel they are .Then  write another list of the things that you dont like about your partner and write them down to.

Then just leave the list for a while maybe a day or two  and look at it when you are feeling emotiinaly a bit calmer than you were when you wrote this post. And when ever  that is way up the two lists ,and you will then write a list of the things about him you could live without and then  write a list of the things you feel you couldn't  live with out and would always miss.  Be brutally honest with yourself about these things. 

And I think by then  this will give you your answer  hope this helped .x
