There are only very few reasons anybody can be excused for not responding to contact if you are involved in a relationship with them, as far as i am concerned they are;

a.) they are physically not capable of responding to the contact (incapacitated)

b.) they have no money or means to make that contact.

Any other reason that I can think of so far, would just seem as an excuse. I may be wrong about that, perhaps other people can think of other reasons (I am always willing to admit I might be wrong since I am not a computer) but saying you are too busy to respond to a repeated request via even just a text which takes 20 seconds is bullshit. Any person who tries that one on me would be dropped like a hot potato because I been down that road before and I know what I want from a partner and that isnt it! I dont expect people to respond to texts straight away, but I do expect some contact back within a reasonable time frame. This is all assuming I was in a relationship with them and not just a casual fling.

Best of luck to you.
