Keep seeing it pop up on my fiances phone wondering what the he** it is...help me . been done wrong before I'm hoping he's not another regret...gotta know it's right before we get married. He's very weird when it comes to me and his phone.
Unfortunately there are quite a few apps out there that look like 'T's, so kinda hard to pinpoint without an actual picture. Could be Tumblr, Twitter, Tweetcast, vpn apps, etc.
Trust-wise, don't sneak around and 'spy' on your fiancee. Talk things out.
