Has this happen to you in the past or recently where someone is forcing you to be in a relationship with someone else even though you aren't that interested in dating? What should you do when something happens like this? 

yeah, i've been there. :/ my friend tried to keep setting me up with guys cuz she really wanted me to get a boyfriend for some reason. anyway, that continued on for some time, until i finally talked to her, face-to-face, about not being interested in him and in dating. 

so, my advice is to talk to the person, and tell him/her that you aren't interested. otherwise, they'll keep trying to force it onto you. i hope i helped! good luck. 

that is really true. I have people trying to set me up with another peson even though i am not interested at all. it is annyoing at time when someone tells me to date someone that i dont know. so whenever i tell them that i am no interested, they will move away 

Yes it happened twice, when my parents are pairing me up with their friends' children. It was pretty annoying but then I can't do something about it since it's part of our culture. Seriously, I wouldn't be surprised if one day they'll arrange a marriage for me.
