Hi guys!

So basically, me and my partner had an awful argument last night, and usually in the past when we've argued he's messaged a couple of other girls on Instagram. But I thought he'd changed and he's said he's not like that anymore, but basically I've found a SIM card and a pin so he can take his other one out. It was never there before and I wasn't even aware he still had his old SIM card! Am I being unreasonable to think he's got a secret SIM card to text other girls? I'm such a paranoid fucking mess half the time it's a joke 😶

I just need advice as I'm at a massive loss!
