Serious question?? Opinions etc welcomed

So I’m 24 weeks pregnant with my first and with my boyfriend of two years... it’s great I love him very much, we’re best friends and get along great even though we clash sometimes. To moms, is it normal to worry if I say how I feel sometimes or wana get mad at certain things and don’t because I’m worried it’ll get to far or if I second guess things sometimes an think about if I have to do this alone, worries me for my daughter not myself, I worry if we break up he won’t be her dad, won’t be ther when she’s born or after.. but if we’re together I know I don’t have to worry about that so I hold back a lot... is this normal is what I’m asking? I mean I knows it’s a lot an I just went on a super rant asking. But please tell me your input if you think I shiuldntworry about that either way an just focus on being a good person an Mom for my daughter?? Or stress if her dad is gana b there for her regardless.. with or without me. ? Opinions PLEASEEEE an thanks 🙄😣🤷🏼‍♀️
