What should I Do

Back story: ( Im going to try to make this short ) My boyfriend and I have been together two years, he has a job but never any money because he pay bills. he only makes approximately 500 every week, sometimes he even has to borrow money for me to catch up on his bills. A month ago he recently lost his job and has been living off his unemployment.

The other day I was walking in the mall and met this guy and he was trying to get my number. I told him I had a boyfriend, but he just wouldn't leave me alone would say things like " oh you can't have friends " and kept following me trying to get my number. So I gave him a fake number to leave me alone ( I said my number but the last two

digits were wrong ). Then, he called the number in front of me. I then was walking away and he realized it wasn't the right number and came behind me. I eventually gave him my real number. He was still following me around asking questions trying to get to know me.

He was telling me things like he wants to take care of me and he was letting me pick out clothes and shoes I wanted from different stores. After we were done shopping he dropped me back off at home since I used uber to the mall. Since then I have been texting him but he wants more from me .. which I was expecting.

Today we stopped texting because I told him once again I have a boyfriend and I shouldn't be texting him. He got mad and asked for the stuff he bought back for me. I told him no and now he's on the way to my house while my boyfriend is here. What should I do??? I'm freaking out because I told my boyfriend I bought those things.
