She won’t leave us aloneeee

During the summer, my boyfriend and I took a break.. during that break, he got a new girlfriend but left her and asked me to take him back, so I did. The girl was his neighbor so every time I’d come over there, she’d come outside and argue with me so eventually we fought. After the fight, she got her friends to add me on Snapchat and would threaten to come wherever I was (I had my location on).. so I blocked the girl and her friends. She made a new account and saw that I was with my boyfriend so she texted him saying she missed him with hearts, obviously causing an argument between us.. so he blocked her number and we got over it, we think it’s the end of her craziness but now she’s back 😂 she’s friends with my boyfriend’s mom and is now saying that she’s pregnant by him.. he texted her telling her not to lie on him but of course she denied that she ever said it. At this point, I am just ready to give this girl what she wants and leave my boyfriend because it’s becoming too much
