He doesn’t want me anymore

My bf has always had a pretty high sex drive. At the beginning of our relationship he wanted it all the time. It was always so fun & literally the best sex I ever had. Not so long ago we found out we were pregnant. We were soooo excited. Unfortunately it ended in a miscarriage. We were devastated. I think I healed a little better than he did. He’ll still sometimes say “I lost a baby”. Breaks my heart. What breaks my heart even more is that he actually said to me “before the miscarriage, I wanted you all the time. Now I’m able to control it a little better”. He didn’t mean any harm but it actually shows when we have sex. It’s not as frequent & he’s not as into it. Before when we had sex he did everything and anything to see me lose myself. Now, it seems he just does it so he can get off and actually comes before me every time now, I haven’t come in weeks. He’s assured me that he doesn’t see me differently, still loves me etc. is ready for me to be pregnant again- but I can’t help but to feel he’s not attracted to me as much since I lost the baby. Is there something I can do to spice us back up? Anything I can say to him? 😪
