Brother-in-law divorce

So my brother-in-law is going through a messy separation/divorce. They have three kids (13, 7, & 3). These kids are thrown from sitter to sitter and both parents are partying constantly with absolutely no stability for the kids. I used to watch the kids until they took advantage of me and didn't pick their kids up. Now, his girlfriend who is 10 years younger than him had her IUD taken out and told me she wants to have his baby. They have been dating for 4 months and he is still married! I have been TTC for 7 months and if she gets pregnant before me I'm going to scream! They can't take care of their kids now. Ugh. This is an added stress I really don't need. Am I wrong in feeling this way?
