My parents hate my boyfriend! 💔

My boyfriend is 9 years older than me and has a 3 year old child. My parents loved him until they found out he had a child and now they've told me that if I stay with him they won't maintain a relationship with me. My dad threatened to not walk me down the isle at my wedding if my boyfriend and I do et to that point and want nothing to do with our future children. He's an amazing guy, works hard, makes me laugh, looks after me, spoils me and loves me. I'm so torn and the situation is very emotionally straining. Any advice ladies???
