Advice please 😪

My ex and I broke up because it was long distance and he didn’t know if he could do it anymore it’s been 4 months and in those 4 months we still talked everyday, especially after school. Well last week he told me he loved me and wanted to marry me one day cause I was the only girl that knew him and that he regrets everything . Well he got back into contact with this girl that he use to be friends with and she calls him several times a day. Apparently she’s has a fucked up life and she calls him if she upset idk. But I’m just so jealous. Because I’ve started falling for him after he opened up to me and Idk what to do I’m scared of being hurt again. I’m scared he’ll leave me again but for her. I don’t know what to do I’m just so scared I don’t know what to do but cry.

Apparently it’s the wrong girl, she’s some girl he met on kik because he wanted to talk to new people. She called him at least 100 times yesterday. 5 or more calls in 1 hour. Apparently she likes him, and likes hearing his voice 🙄. He said he still loves me though and I made him swear that if he has any sort of feelings for her to tell me so I can start to get over him.
