Samantha • Leila Jade's mommy 👶🏼💘
I'm 21 years old and a mom to a beautiful 6 week old daughter that I love more than anything. Me and her father have been having major issues and I don't want to be with him anymore; I can't afford anything on my own exspecially now with a child... that's the only reason I think about staying,,, what do I do? I deserve to be happy too right?
