Baby Daddy # 2

So I’m 21 years old. I have a littlegirl who is turning two on the twelve of this month. I just found out last friday that I’m expecting another baby (five weeks along so far) . I’m scared. Honestly I have a hard enough time with just the two year old, how am I going to handle a 2 1/2 + newborn? My daughter’s dad does not help me what so ever. FRUSTRATING! and my boyfriend now hates him because he doesnt do anything to help us. My boyfriend is very excited. He is 27 and also has a two year old daughter of his own. I am not worried about him leaving and not helping like my daughter’s dad did. I’ m just worried b/c he is in a little bit of trouble rite now over somethings that were not his fault. I dont want him to get locked up durring my pregnancy and I definently want him to be there for the delivery / when I bring the new baby home. I told him he midaswell go and sit his time out now while I’m only 5 weeks , but he says if they try to get him for anything else and he ends up getting more time its going to be harder b/c then he’ll miss the pregnancy AND the delivery. So he wants to wait it out as long as possible. I’m just scared. I know I’m keeping the baby b/c I cannot have an abortion (I’d feel horrible for the rest of my life /// same with adoption ) this is my baby so I’M TAKING CARE OF IT , not anyone else. I just dont want him to go… ughhh! what to do what to do…?
