TS , I would say forget it to this kinda girls .
First n foremost , if u are serious abt her .... life would be really tough down the road .
She has lost faith in Men . im sure something fucked up happened to her that's why shes raising her kid all alone . even if she accepts u , there would be a lot of problems like suspicions and prevention of what happen to her before .
I would say , have fun with her but not get serious ....But I don't think you should hurt her further .
let her be ... im sure shes going to call u
