Am I truely the Only one....

I have briefly explained my life so you can imagine the chaos that I constantly face on a daily basis. Although I am married, I have not been married my whole life nor my children's lives. My husband is one of those very unique men that can look at something so trashed and see something worth saving. My two oldest children's father is what most people call a "dead beat dad". He does absolutely nothing for my children and despite my efforts to appease my children they are never succesful because they still ask about this LOSER! It is so infuriating at times. I could talk negative about this guy for days, maybe even weeks but no matter what type of father he is, he is still their father. I was a pregnant teenager, I made my bed and definetely laid in it. I have recently considered asking him to relinquish his rights so that we (my husband and I) no longer will have to worry about him trying to step forward when they begin to do the amazing things that I know they are capable of. Am I the Only one!?
