I’m selfish?

I just broken up with my boyfriend 4 days ago he was super toxic and just didn’t cared about me and the baby I left him for good and I just feel so guilty for giving my baby a broken family and I constantly cry over him but he over there wigh his new gf and everything I’m currently a teen mom Aso I just feel very lonely sometimes tat I have no one here with me but obviously he was only using me for shelter and sex #firsttimemom #pregnancy
