Why would he think he could do that???

My ex walked out on me and my dd when I was pregnant. We didn't get visitation or child support orders till she was 2 and he never gave me anything for her. He has a "friend" who is pregnant and found out that it is a girl. He called me and told me that he had told her that she could have some of my dd's clothes from when she was a newborn and she would be coming to my house to pick up some of them. I told him no way, I bought all those clothes and I am keeping them because I plan on having more children. He said that because she is his dd too, he is entitled to half of them. He also told me that he wants to give her the stroller that his mom gave me at my babyshower. I told him that I used it for three years, so it is in pretty bad condition and that even if I hadn't donated it to goodwill, I still wouldn't HAVE to give it to her because it was given to me as a gift. He said that she doesn't have any money to buy these things. I told him if I wasn't going to use them again, I would have already donated them to goodwill but as I do plan on using them, I am sorry that she needs them but it's not my job to provide for her child. He got mad. I almost wonder if the baby is his because he is getting so pissed about it. He is halfway across the world for the Army but he did come on a visist a few months ago (didn't bother to see my dd though). I just can't figure out what in the world he was thinking trying to give her things that I bought!!!!
