Family vs Partner

I need some advice ladies, long story short last year in December I lost my baby with my ex (he was never keen on the idea as , I was 20 at the time he was 23, we had only been together a few months but things obviously didn’t go to plan and he retreated into himself away from me and I broke up with him after I lost the baby because I was hurt that he could abandon me) since then though we have stayed on good terms and have been seeing and talking each other regularly ever since nearly every day or some time a couple days a week if we were busy, and I realised that I never stopped loving him no matter how much he did hurt me I understood that it was very scary for both of us to have been through, he was mentioning about getting back together on and off since we split but I finally said yes as I really missed just our simple nights together and how he made me laugh and our dumb jokes, however my parents (dad especially) are not keen on the idea of us getting back together and when I try to talk about him or anything I get shut down and shouted at, I feel more hurt by my parents (dad) not listening to me about my point of view as he was a big part of a traumatic part of my life and they don’t seem to understand why I could still love him and want to give it another go, I just feel like this is a personal choice and it should be respected and listened to, he wants to sit down and talk with my parents and listen to what they have to say and apologise to them for everything (this was all his idea not mine) he’s really grown up and time apart has made us both realise we are a perfect match and together we are much better then we are apart, how do I approach this with my family? Any idea?
