Finally done with this sorry excuse (kind of long)

I have officially had my first drink later having baby to calm my nerves. I’ve hardly slept at all... and in my sorrow I seem to randomly burst into tears. I’m trying my absolute best to stay strong for my son.... but my heart physically aches. I’m literally embarrassed and mortified to ever have even been affiliated with the likes of this man... and my heart breaks for my son. He simply does not need to be exposed to any of this. But I unfortunately still love him and it leaves me reeling. How could I have not seen sooner? Do I have to Allow my son around such an unpredictable and unstable man simply because he is his father? Will he suffer if I keep him from him? 😪😪😪
