I need some strength

So I’ve been a little unhappy lately with my partner. We have a 2 year old and we recently found out I was pregnant with our second and he’s really not supportive. He’s been really disrespectful lately as well, going out instead of being home. Saying all sorts of crazy and calling me names. Last night I told him enough is enough. I’m tired of being disrespected and being an emotional punching bag. I told him to sleep in the other room. But I honestly feel like packing my stuff and leaving, or should I ask him to leave? I’m currently the one paying the rent because he experienced a financial hardship. Which I’ve been supporting most of the bills and the rent while he recovers from that. He’s working but he’s paying off a big debt. I need advice, I’m sad because I’m supposed to be happy during my pregnancy and it’s hard putting this smile on my face for my little one knowing I feel like crap inside.
