When I got pregnant with my daughter, my boyfriend left me because I refused to have an abortion. Ultimately, he came back when I was about four months pregnant. He might always come back and realize his mistake if he so chooses to leave. Regardless, he's financially obligated to the child, so, I wouldn't worry too much. Even if my boyfriend had never come back, I'm so glad I kept my daughter, she is the light of my life. Motherhood is amazing, you should join it
