Am i in a mentally abusive relationship

Please read this so it makes sense, I don’t know who else to turn to but I never been in a situation like this. This new guy from work has been starting at me for months and trying to get my attention for weeks and weeks, I finally one day gave him my number and we started texting. I’m 25, he’s just turned 23. We’ve only been ‘ seeing each other for 4 weeks and been out together 4/5 times. I do enjoy being in person with him but over text he’s crazy. He tries to make me have my location on 24/7 and if I didn’t, he’d argue with me. I went on holiday for 2 nights as was already pre booked and he was screaming at me over text saying I shouldn’t be leaving my man and that I can’t go on any more holiday, he also making me send pics of me and my girl to prove I’m not with a man. He gets so jelous ire crazy, numerous times he’s fell out with me because he’s angry I’ve had boyfriends before him and had experience with other men. Also I’m from another county so I have family in Europe, I was with my ex for 8 years and obviously I took him to meet my family In Europe and my house and he was texting me the other day saying why the fuck did you take ur ex to Italy and why did you introduce him to ur family ?? Like wtf is he serious. And he always brings up my ex saying why did you do this ect. He also keeps flipping his shit on me for no reason, we fell out because he said to me my ex has ‘ had more of me than he has’ because I wouldn’t send him vids of me naked(which I never do )and then said he felt angry and annoyed and jelous, and because I said he was being pathetic he started telling me to never speak to him again and to go away and that i bring nothing to do the table, like he’s one of them that’s angry he will keep sayin and saying stuff till he burns out. He tells me to not talk to him and then he will scream at me saying im speaking to someone else and i can’t even attend to my man. Like I genuinely have never seen anything so bizarre in my life. How in person is he the nicest sweetest person but the second I’m away from him, he’s causing me terror and he’s making me feel so shit now. like I feel on egg shells constantly and I would never ever let a man make me feel like crap, but this guy really has made me feel like rubbish. Like we fell out tonight after the video thing, he kept telling me he loved me and I was all he thought about and then he switched saying he hated me again, idk what to do. He’s trying to ruin my life I can feel it. Well I already know the answer to my question, I just feel like mentally drained and he keeps telling me that we are never over and that I am his for life whether I like it or not, so when I do ignore him or delete him he pesters me again and I end up back in the same cycle.
