Baby daddy issues 😢

So my sons dad and I aren't together right now , he was in a new relationship and everything . I guess they're broken up now  And I respected it ... But now he lied to me about having another baby by someone else .. And I'm honestly just devastated . I still wanted to just have my kids by one person and get married to this person ... Our engagement was called off ... A few months ago . And now he's saying stuff as if he doesn't even wana get back together but I been here waiting on him at home taking care of his son ,.. Now he has a daughter I feel like he has a new family and I'm so jealous 😢😢😢😢I was supposed to have our 2nd  baby last month but the baby didn't make it ... 💔💔💔 I just went through all this by myself , it's stupid to be depressed ?? but I am 😔😔😔 deeply  Asking for opinions and comments pls
