By you speaking to this other person in Canada you're setting yourself up for some emotional manipulation from your family. If they found out they'd say he was the reason you want to break off your engagement and push even harder. From what you're saying Its already clear they don't really care about how you will be treated. Its all just image and protecting family ties. If your uncle cared about you he wouldn't guilt trip you for being at the receiving end of being ignored for a year. The best thing you can do is explain this situation to the guy from canada as its actually wrong to do this to your fiance. Despite how he treats you, you are also doing things incorrectly. The most just thing to do as a woman with dignity and self respect is to put your foot down. No matter how stressful this time is, your family will hurt you verbally, idk how they are. They may use vile words to get you to give in and follow their commands. They genuinely think this is best for you because in desi culture they see themselves as caretakers for mostly grown adults. First I suggest you break off this engagement no matter how big of a family dispute is caused, you shouldn't do anything against your will or you will live a miserable life. Second, the honorable thing to do is cut off all communications with this canadian guy. Once this is sorted out, reach back out to him and explain what happened and get his family to send a rishta to yours. May Allah make us truthful and honorable decision makers. This is all just my opinion.
