What to do? 😔

We're having our 1st baby soon & we broke up a few months ago because he's tired of me yelling at him about the loyalty & im tired of yelling about it. I want my family.. He says he loves me & I'm his future wife  but he's always texting & flirting with girls. He said when the baby comes it'll be better but why should I wait ? 😔 what should I do glows? The situation puts me in a slight depression. Because I want what I want and I'm not getting it.Â
