Hello sir, I am in a relationship for around 2 years. We both are very much in love and we want to get married. But he belongs to low caste in India and now I fear if it will affect me in the future in a way that people would discriminate with me based on the caste thing. I am very much confused. Please advice me.

Traditions and rituals amongst castes differ a lot. Try to find out that whether you will be able to adjust to them and that too life time. This is the most important consideration and then comes the issue of discrimination, which you have to face. If you are mentally ready to face this in your life then you should go ahead otherwise, take your own time to think and decide on this.
