Holding on to the fairy-tale ending.
I’m sure most of you already know this, but just in case, let me be clear: a child is not a guarantee of marriage. If he wasn’t compelled to fully commit before you gave him the booty for free, it is unlikely he’s in any rush now. Don’t waste your years waiting on your child’s father to “come around” simply because he’s the dad. You deserve the type of love and companionship that makes you happy, too. If you were actually in a relationship, go ahead and give it a solid try, but don’t hold on to a dead relationship or wait on him forever. Now, if you were just a “buddy,” well, you already knew the deal. Be honest with yourself and move forward.
