need some serious advice without judgement

im currently in a bad situation. my husband whom i have 2 kids with has packed up and said f you i dont want to be married. what makes it worse im 13 weeks pregnant with number 3. and he says for everyone's sake you shouldn't keep it because it would be hard on all of us especially

if you ever wanna find love again no guy will want you with 3 kids. and im on the fence about keeping it. im scared of being alone and struggling. and if i keep it my family says they will not help me. idk what to do.
