Dont know why im stil sticking around

I been with my babys father since 2019… had our first baby in 2020 then our 2nd in 2022.. our beginning relationship was good I thought i found the man of my dreams.. gunna be married and live happily with no drama or cheating etc… i was wrong… he treats me so bad idk i should have left along time ago but i thought he would change.. he calls me bad words like hoe bitch cunt… for no reason at all.. then he has hidden social media snapchat etc talks to girls on there.. has tinder .. he says he never met up with anyone and cheated like having sex etc but talking to girls on social media giving them the time of day getting numbers tryna meet up witj them is cheating.. im with him because i dont want to be alone again .. and a single mom💔 i keep waking up thinking he willl change and stop doing that but he keeps doing it like idk if its on purpose or just he has an addiction or just doesnt care about me.. he never never tells me he loves me posts me on anything..he never massages me not once when i was pregnant he always just stressed me out and argued wit me .. im the nicest person ever , loyal person .. cheating and talking to a guy while im in a relationship is the last thing on my mind:. We do live with each other. Im just so depressed lost alone .. like idk what he wants like to be single or with me everytime i even ask him “are we together “ what are we? What are we doing?” He gets aggressive at me and defensive 💔 doesnt even say an answer.., i never been in love sadly.. I thought he would be my husband and be happy he was different when i met him first…💔💔
