My Duo Curse

So I think I'm cursed when it comes to duos or playing ranked with other people (queued and such). It seems to me that every time that I queue with other people I end up losing. I also found that a lot of people who friend me after games start spitting toxic remarks throughout the game and try to get me reported for their actions. Believe me when I say that all they do is spam the same insult over and over again to their team and then call you toxic. The fact that people are like this, whoever ends up friending me, is really just odd because they seem to be the same over and over again. Why do I keep meeting these "supposedly nice people" who spam invite me every minute of their existence an invite to their ranked games and end up doing bad along with being overall toxic? Am I cursed or is this a thing that many people have faced in the community?
