I felt the most unhappiest and unluckiest preggy mom ever for my second baby...

Long story short, as much I've wanted to be happy to focus and be grateful for the little one inside.. sometimes I couldn't resist being feeling unlucky and unhappy, coz of the multiple betrayal I deal with the father of my baby. Multiple lies, multiple texts I've seen asking nudes from different pokpok, following naked women on Instagram or joining a channel on telegram. I'm about to give on October 15th, I should be excited about this, and yet, I'm feeling fearful and unhappy coz I'm not really comfortable being with someone I can't really trust... Live might shorter, but still not a good start journey for me... Mom's, I am really feeling down, any advice would like to share? 😢😢😢
