Having a hard times trusting

Lisamarie
I'm having a hard time trusting my love of 7 yrs, resently I found some text. Now he's always has had a lot of female friends but this chick came out of nowhere, we've known each other since we were 12 and 15 he was my first love and my first everything. It took a lot for us to reunite. My question is am I overthinking because we are ttc and I'm all emotional, I've never mistrusted him before and he has never giving me a reason?
