There is more to the discord than "the label." If you can recognize what causes your discontent it may be easier to resolve the issue. Your "baby daddy" may feel that he is the cause of the issues when you are together and that may be why he wants to give it another try with the baby as his motivation. It could be a commitment thing on either side of your relationship. Until you know what the root of the issue is, you shouldn't risk a bad breakup involving your child.A child has such advantages being raised by two parents. Maybe this baby is what you two need to help you grow together and be better together than you are apart. You have two things to think about now, your wellbeing and that of your baby. If you can really figure out what went wrong when you were together it may help you work things out or at least figure out what you need in a companion. It sounds like you care about each other. You might consider counseling, together or on your own, to delve into this problem you have of being "a couple." It may make it easier to understand what the problem really is and move forward.
