Stay away from my man!

So my bf cheated on me while on vacation w another girl. (At first he told me he was going alone). Then, he changed his story because I saw that she tagged him in pictures on IG and told me that she was his cousin. I did a little more snooping, grabbed his phone, got into her IG and saw them KISSING!!! At first I thought she knew about about us and I lashed out at her. Turns out she didn’t know either, and I apologized. I took him back because he’s been treating me well since then. A few weeks pass and she reaches out to my bf and tells him she “suffered a miscarriage” and she wants him to make some memorial for this fake baby. I don’t believe that shit for a second. I demanded her to show proof and she told me she wasn’t under any obligation too and that’s between her and my bf (I forbid him to talk to her again if he wants to be with me). It’s like bitch, I know you’re still in love with my man, and making up stories isn’t gonna make him come back. He’s mine! Also, lose some weight! Running on the treadmill burns more calories than your mouth!
