What to do with my love ? Relationship advice pls..?

Hi! I've a girlfriend from a year. I'm a brahmin and she is SC.


My parents are orthodox. I'm now doing my 3rd year engineering


and she's also doing same but diff coll. My cousin loved a


vegetarian girl but still my parents are not reacting to him


correctly since she is diff caste. Now seeing this I'm worried


of my relationship. I don't know what to do. I'm in confusion


with ma n her life. Wheather to leave her or not. But she will


sucide or do something stupid if i tell her to leave. also even


I don't wanna leave her. So, can you pls suggest me what to do next ?
