6 weeks after birth and I've lost him. How could he.. leave with no explanation.

My fiancee, not my fiancee my man not my man unbelievable how someone could move on so quickly and when i say quickly..i mean day after she was born. What a jerk.. Im so lost at times i feel like hurting him like he hurt me. He said i didn't listen to him and that I lost all respect for him. That doesn't justify the fact that he started a new life with someone else and left me to take care of the baby on my own. He moved on without me..😥

The man i thought i knew...
