Before Christmas this girl from work came over to my house after a few weeks of talking. She has been on and off with another guy because he only uses her for sex but she has feelings for him. When she was at my house the guy kept blowing up her phone. When she left I blocked her. She approached me at work after this and was complaining about the other guy. I asked her to block him, she said no. This happened a few times of the blocking and un blocking but she did not ever block him. A couple weeks ago she left me a note at work and I responded (let me know when you are not fucking some other dude). She came to my work area the next day and started talking with me. I had her over that week and we finally had sex. When she left my house after two days of hanging out and having sex, the other guy DMed me and said “Shanna must have been with you”. Did she tell him she was with me? Initially I did not respond and let her know the guy DMed me. The next week I asked her to block him and she said no. So I was mad and opened up the guys DM and told him I whipped her for an hour and cummed in her. She got furious and blocked me. Was she using me to make him jealous for the last few months?
