emotionally abused??

I'm not sure what to do here. I have been married for 3 months now. The beginning of our relationship, everything was perfect. My husband was so sweet, would do anything for me, I was always being told how beautiful I was, he was always making sure I knew I was loved. Fast forward to now... if we get in a fight; I'm being called a bitch, a cunt, a dumbass. He's making comments like "idk why you said yes to marrying me", when I try to talk things out in a fight, I'm constantly getting yelled at! I know that every relationship has different views on porn, but to me, it's disrespectful, and I am very against it, it really grosses me out. Well... we got in a fight 2 nights ago. I went to the park with my daughter to cool  down. (He stopped smoking because I didn't want my baby girl growing up around it) he had went to the store and bought a pack, when he knows I'm not okay with it. He called someone we agreed he wouldn't talk to because that person betrayed him and highly disrespected our marriage. I come back, and he's trying to do anything to make me leave. I didn't. Last night, everything was fine. I had got on his phone to look up something, and there's porn. It's been deleted from history but somehow it's on there letting me know he's been on it. I asked him. He stayed quiet for a bit, then says "I swear I didn't touch my dick to it, I pulled it up and backed out of it. I just pulled it up so you'd find it on my phone and it would hurt you. I wanted to hurt you when we fought, but I regretted it so I deleted it off my history".. anytime we fight, it's ALWAYS my fault. He cant take the blame for anything he does. I'm tired of feeling like I can't even talk to him about anything like a married couple should, because his temper is so bad. Last night while fighting, he just did not act like he cared if I was there or not, I was trying to work it out. Bawling my eyes out. Having an anxiety attack, and he just said "okay." When I was done pouring my heart out.  I'm on the verge of leaving because I don't want my daughter growing up in an unhappy home. I am tired of feeling unwanted, I want to feel beautiful again, he makes me feel like a piece of dirt on the ground. But when I leave, I think of who he's gonna be with, how I'm going to cope with not having him anymore (I have BAD anxiety and he's someone who's been by my side everyday. I'm attached) my daughter isn't his, but she's gotten attached as well.. I need advice. I feel like I can't talk to him because it goes in one ear and out the other. Do I just give him space? Idk! Sorry it's so long. I really need advice.
