Mom thinks my girlfriend doesn't deserve me

I am a medical student in my final year. I truly love a girl but my mom doesn't agree she believes I deserve better. She says that she doesn't like her family and she also says you have a promissing future so u will get a lot more girls and better ones. I don't wanna leave her. I don't know what to do. Should I just focus on studies and leave everything or I should stick to it. Cuz if we have break up late then its gonna hurt more, so I don't know what should I do please someone give some good suggestion or idea. I have tried all tricks :(

Sometimes you don't see what parents can see.

Why your Mum thinks that she does not like her family, you have to find reason for your mum's dislike towards your girlfriend and make your GF to work on it. Further if you know root of issue, you can work on it with your Mother too.
