Retorting to hate someone because of ignorance and denial is natural to human soul.
I don’t know where you are coming from, and what cultural thing stops you from talking to each other, but if your to be wife is really that spiritually and culturally strong in her values, then you’re going to be a very happy man after marriage. However, I apologize in advance, but I feel that real reason is something else. You two should definitely talk about it before its too late. Probably she loves someone else, probably she doesn’t like your sticky behaviour and is only marrying you due to family pressure, maybe all that you’re thinking is really just unnecessary thoughts and your to be wife is really as good as she claims to be. But you won’t be able to know about that without talking to her.
If its the cultural thing that you can’t see her or talk to her via voice, try to message her and ask her if she can talk to you for just one time via messages, before the two of you get married. Tell her what you’re feeling and try to find out what is it thats stopping her.
I’m talking about the real reason. For that, you’ll have to earn her trust. I’ll tell you how to earn her trust. When you message her, don’t go straight away about how you’re feeling or try to know the reason. Treat her with kindness. Ask her about her health, her family’s welfare, her mental state, her recent problems and everything that will make her believe that qhether you love her or not, atleast you genuinely care about her. Don’t make it all about yourself brother. She will only understand your problem and your situations after you earn her trust, after you try to understand her problems and be with her in her tough times. Don’t look at her as something made of different material brother, she is also just a human with feelings, just like you. Life might be very tough for her as well. Probably this marriage is being forced on her, but if you stay like this and eventually get married, your married life will turn into hell, filled with toxicity, suspicion, hatred. Think about her as well, my friend. Treat her gently and kindly.
Love is a strong word, and so is hate, but they are not antonyms, antonym of either is indifference. I hope you have a very happy married life and may your wife be the person who makes your life a heaven.
