Problems basically

Okay so, me and my boyfriend were talking for a couple of weeks. I was thinking about the fact that me and him never really have anything to speak abt and he cheated on his last girlfriend with me and i didnt know abt her until his cousin (My bestfriend) brought her up. 🤦🏼‍♀️ So i want to just talk longer but he already asked me out and i said yes cause i was really happy and it was a very happy moment. So, my guy bestfriend texted me and he has a girlfriend and they’ve been on & off for the past 2-3 yrs and he was flirting with me. I know him well although we recently started being friends and he sent me his dick.. 😳🙃 So, i was sitting here in my bed waiting for my boyfriend to get home from the gym. The bad part abt this is he cheated without mercy and my best guy friend was cheating basically on his girlfriend and im scared that my boyfriend will cheat and my best guy friends girlfriend will possibly beat the fuck out of me because she recently got into a fight with this girl at school and she is suspended..
