My life as a mom of twins...so far

 Life as a mother of twins is difficult. You always get people saying that they wished they had twins. In my opinion, people dont know what they would be getting into. You'd have to be there for 24 or so hours to realize, its not as easy as some people think. I met their father in March of 2005. He was great and we had alot of fun. I had just turned 18 a few months earlier, in January and he had turned 22 that same month. Things were great between us. Then the talk about having a baby came up. I think i was the one who brought it up first. I had wanted one so bad. Little did I know what i was getting into. Well August 22nd of 2005, I had gone to take a pregnancy test and sure enough, I was pregnant. I was happy and at 18, I was going to be a mommy. I know i was young and I had wanted to take it back, but I wouldnt change it for anything. September 22, exactly a month after finding out I was pregnant, I had some bleeding at 12:30 in the morning. With it being my first pregnancy, I was very worried. So my mom had taken me to the hospital. At the time, the ultrasound tech wasnt there, so they had to call her to come in. She didnt arrive until about 2 in the morning. That moring I found out I was having twins. They were born on April 21st of 2006. They are 13 months old. Its been really rough. There dad is really no longer in the picture like he should be, and my boyfriend that I have now has been "Dad" for the last 7 and a half months. Their dad buys them A pack of diapers every week to every other week. He chooses other things, such as video games, cds and drugs, over spending time with his girls. But thats on him. I'm not preventing him from seeing them at all. Although lately I've told him that if he doesnt start helping me every week like we had agreed then I would either not let him see them, or I would go for Child support. I dont think I'm wrong in telling him this, especially with what he's put me through. Am I wrong for thinking this way? In the last 7 months, he's seen the girls a total of 4 times. His family makes such a big deal about me not being able to bring the girls to see them, when I dont drive and Its impossible for me to take them on the bus by myself. But yet, they just went out and bought the twins' dad a 300 dollar video camera and they cant buy anything for the twins. Their dad lives at home with his mom, her boyfriend, aunt, grandma and grandpa. His grandma has recently been making remarks such as, "Your buying them diapers, again," "They dont deserve you buying diapers for them."

 I've pretty much taken care of the girls by myself from day one, with a little help from my mom and my boyfriend. Their dad had only been in their life, actually living with us and taking care of them, a total of 1 and a half months since they were born. He's missed a whole year of their life. He's missed them rolling over, sitting up, crawling and the most recent, walking. I'm at wits end trying to figure out what to do about this. I am completly clueless.
