Doing it all myself???

I have to wonder if maintaining a relationship is what I want to keep doing?? I mean right now, I feel like I'm doing all the work. I wake up, get the kids ready, make sure Isabella has everything for school, send her off to the bus or drop her off, make sure the baby is dressed, leave him with my dad, go to work for 8+ hours, get home, do the kids laundry, do my own laundry, make sure permission slips are signed, homework is done, make sure appointments are scheduled, feed the kids dinner, bathe the kids, get them ready for bed and finally put them down. Now every day isn't the same but the vast majority of it does not chance. With every day that goes by, there are new challenges to face, new adventures that we are dealing with and to be frank, I feel like I'm doing this alone with the kids.

If it isn't the actual help, then it's the financial aspect. I sink every paycheck into clothes for the kids, food for the kids, bills for the house and my father's medication. What does he do with his money? Hell if I know. I think my biggest problem as of late is his ability to prioritize. He knew on Friday that Isabella had a dentist appointment scheduled for today. I asked him to please provide me with $50.00 so that I can put in the other half and pay for her visit today. Saturday came and went...and I was duped again into putting a $55.00 purchase on my card (oh I'll just give you the money later)...with no money for the appointment. Sunday, he woke up and jumped right into playing his video games. No spending time with his daughter. or with his infant son. He took some time to drop off his oldest son and to pick up lunch, but again neglected to pay back the $55.00 that was spent on Saturday or give me the $50.00 for his daughter's appointment. Instead, he went on to spend 12 hours (that's right, I said 12 HOURS) playing his video games. So this morning, he's rushing around getting ready to work, complaining that he is late when I asked him about the money. Of course at this point, he's annoyed. I told him that I need it when he gets home and he left in a huff.

Am I wrong for acting like this should be a partnership and we both need to be pitching in? This is ridiculous that any kind of talk, whether it be financial or not, turns into a pissing contest. I shouldn't have to pull teeth to get him to help me. I shouldn't be doing this by myself! In talking to my father, he feels that I'm getting used and to be honest, I feel the same way. I'm already doing this all by myself...if it continues to be like this, I'd rather be by myself as well. In a way, it feels like he wants all the perks of being a father and husband, but none of the responsibilities.
