She didnt say that I dont love you, and she dont say I love you.

when ever I ask her do you love me she dont reply, when ever I ask her will u marry me she dont reply, now last time she said to me what are doing abroad I replied I am engineer here. I said to her do I come back I not, she replied I dont know?, I left country bcoz we were in tense relation, after two years I messaged her she replied me, my mom and brother are coming on umrah but we can not take ur daughter on umrah there is time u must pray that I will alright, I always call her little sister as my daughter. plz tell me why she always dont reply clear.

When people love you, they want you to know it, so they tell you.

If she never says that to you she at least has doubts about how she feels.

However, If you ask her directly and she doesn't answer at all, I'm sorry to say that sounds like she doesn't want to make you feel bad by telling you the truth: that she doesn't feel that way about you.
