Don't know whether he actually wants me or not

Me and my partner been together nearly 2 years and over the past few month he has said some really hurtful stuff to me ie- I'm fat need to lose weight, I'm ugly, having a go at me over ever little thing, telling me he can get who he wants and he doesn't need me, his ex was a better partner than me etc it all seems to have been since I miscarried our 2nd child (we have one living child) and it's always when he gets angry which lately is alot. Just looking for some advice really he says he loves me and only wants me and our son but then says stuff like this I'm jist so conflicted and deflated right now 😥😥 also only miscarried end of march 😔
