What would you do if you found out that your parents didn't like your SO?

I’m having a hard time here. My boyfriend and I have been together for almost two years, and I love him. We’ve talked about getting married, and I think that if everything goes right, I would someday.

I usually value their opinions, but I was getting this weird vibe from my mom tonight when his name came up, and when I asked her flat out, “Do you not like him?” she told me flat out, no. She said she couldn’t put her finger on anything in particular, but she had a “bad feeling about him”, and she told me that my dad felt the same way. She agreed that he seemed nice and good to me, etc etc, but when I asked her what she would do if I ever did want to marry him, she wouldn’t answer the question.

I’m very torn and conflicted. I feel very…unsettled. And sad.
