I can relate, as i'm a full time single father who stayed in a crappy relationship, thinking it was for sam. you don't need him, he doesn't give you what you need. there is plenty of love out there, much of it is impermanent. Our culture puts so much pressure on marriage, but it usually causes suffering. Enjoy your freedom, find love and allow the community to help raise your child and he will grow up happier healthier and more well adjusted
