My Life Today...

So, I am 16 weeks pregnant. I am very excited, not nervous yet. I was engaged before I found out I was pregnant, well I ended that about four or five days ago when I had had enough of being miserable. I was not happy with him at all, I wish I had figured this out beforehand. But I am a firm believer that everything happens for a reason. So, he wants joint custody of this baby, and I do not want him to. I guess you would have to know him to understand why I do not want him to have joint custody. I guess I can say that I never really loved him at all. But I do not want this baby to come in this world into a "broken home". But me and the ex do not see eye to eye on anything. He wants to name our daughter Genevieve. No way I will name our daughter that. I understand it is after his grandmother who past a year ago, but heck no. I want to name our daughter Haylen Elizabeth and our son James Rylee. He hates both of those names. He is not open minded at all. I do not know what to do.
