My toddler's father left her home alone

It was only for 10 minutes (so he says) but I can't help but be so upset about this. Our daughter is only 20 months old! A lot can happen in 1 minute so the fact that he left her alone for maybe 10 minutes really shakes me to the core.We were already having a lot of problems, arguing all the time; Mostly about him not caring about anything but himself. I had made up my mind that I no longer wanted to be with him but I still wanted to try to have a civil relationship for our daughter's sake... but how can I after this?! He only has to watch our daughter two days a week while I am in school and now I don't feel comfortable at all leaving her with him. I spent all day calling, trying to find daycare assistance only to be told, call after call, that there is a long wait list. I thought maybe my daughter could go to daycare, while I am in class, where they would actually watch her, rather than staying home with her dad, who apparently doesn't see anything wrong with leaving her alone while he goes to the store for a pack of cigarettes! I'm blown away with how fucking irresponsible he is.Thoughts? Am I overreacting here? I really don't think that I am. I'm going to miss school for the first time ever tomorrow because I will not have peace of mind that my daughter will being taken care of. via /r/Parenting https://ift.tt/2NNx3IL
