Happy in my relationship

So this is my second long term relationship. The first was with my son's dad. My son is 7 now. His dad and I were 19 when he was born. His dad... is not a good person. He treated me horribly for the duration of our relationship, was mad at me when I slipped on ice and fell while pregnant (he refused to assist me), slept through most of the labor, and did/does very little to help take care of his son.

Fast forward, I am currently 21 weeks pregnant. My current bf is AMAZING, sweet, and understanding. I have issues from my relationship with my son's dad and sometimes have fears of some of the same things happening. But my bf is so sweet. He helps me walk on the ice without me asking, he's very involved in the pregnancy(as much as he can with covid), has never made me feel less than completely loved. He constantly reminds me how beautiful I am and gives me encouragement for doing things I struggle with. I know he'll be here to support me throughout the pregnancy, labor, and raising our children TOGETHER. I used to get soo jealous of other women who had amazing bfs(or significant others) that supported them throughout pregnancy and parenting. I always wanted that. I'm so happy that I finally get to experience that.
