newly pregnant first time. hubby has kids

Cathy

my hubby has 2 kids from a previous marriage and I love them and we were trying to concieve and it finally happened and I'm 5 weeks and now he seems off with me and is talking about buying his kids.expensive Xmas gifts and nothing used liked it's the worst thing ever to give his 12 year old a computer we used a handful of times if it's not $1000 then no. We both work at the same job and just make ends meet what happens when I go on leave and only male half . How come when I talk about expensices and bills and how we can't afford to give his 2 kids absolutely everything they want espically when it's.pricyhe rolls his eyes or fights with me .. was it a mistake to want a child with him .. mayne it's the hormones but it's making me depressed about it like they mean more then our child together will .
