my mom always said, you can't make a leopard change it's spots. just because you love someone doesn't mean you should be with them. trust me, you will love again, and after having your baby you will see that you need to consider what's best for the both of you. being a role model is real now. you don't want your child seeing you jerked around by this guy. it's not worth it. protect your child from witnessing this jerk and create a civil and mature relationship, based on one and only one mutual interest -- the child. that's it.
