Why do people do this?

If you don't want to rp anymore or lost interest why don't you just say so? Why do you rather ignore my last response and when I come back sometime later and ask if everything's okay or if they're even alive (because months has passed) why can't you just respond?? 

And i don't mean this for everyone I rp with who just randomly stopped rping with me I mean this for those who I rped with for half a year and more and I thought we were pretty close.. You know I thought we were friends why ignore me? And I know you're online because your profile says so and I see you rping with other people and also your last login date is clearly there =_= did I do something to you that was such a huge turn off? I don't understand and this has been bugging me for months. You guys are the ones that make me just not want to rp or have any real friendships here because you treat ppl like .
