Help.. what should I do?

I just found out I’m 5 weeks pregnant... I was literally gonna break up with my bf. He’s lied to me twice about this girl. And he checks out other girls.

Ugh so I decided to stay with him because I’m having his baby.. he tells me he’s gonna step up and be the man he needs to be..

But Im nervous af. I constantly cry. Because I feel like he’s gonna cheat.... idk if it’s the pregnancy that got me paranoid but...

Should I calm down and give him a chance?

I’m scared to be a single mother... 😬
