Sorry for asking this again but...?

im feeling really blamed for thiss ----> broke up with my bf from 2 years because he cheated, and now he lost his baby with another girl &i feel blamed for it because she got stressed over the fact that me and him still has some kind of connection we would message, text, &call eachother we lived in the same state and we were already doing alot by keeping our distance... someone cheer me up please)= and was this my fault ?
