I feel so crazy! 😭😫

So my husband is OBSESSED with this game called Fortnight 🙄 and always wants to play it with his friends. Lately I’ve noticed he’s been playing a LOT with some chick and he claims he doesn’t even know her name... like really? You play with this chick for hours almost every day and don’t know her name?! It started by him saying she was playing with him and his friend and that his friend was into her, I honestly didn’t care. But now they play with just the two of them and I always know when it’s just them because he puts his headphones on. So far he’s lied to me twice saying he was playing with his friend Chris when really it’s just been the two of them... I really didn’t care at first but now it’s really bothering me. I feel like I’m being crazy but I don’t know why he’s lying to me about it when I’ve never said I have a problem with it... help!!!!
