Thoughts

So today me and my boyfriend hung out with my friends and we all got drunk (I normally don't) and my boyfriend saw this text from a guy in my phone and replied to him like you come near her I'll kill you or something.. But then like as we got more drunk I noticed he always turns his phone off when I'm near.. So (this is kinda not cool) when he was asleep I took his phone because this girl keeps texting him.. And i found texts loads of I miss yous and kissing emojis and many times they hung out when he told me he had work or he was busy.. I found a text of him wanted to meet his friends(i haven't met anyone) and when I asked him he would tell me who she is kept saying I'm overreacting and told me he loved me.. And I'm pissed and hurt Idk what do yall think
