Is My Boyfriend Cheating If He Uses Tinder?

​Dear Mister Mongoose,

I have been in an ongoing relationship for just about 4 years now. I frequently use his phone, because i mean we are a couple. So yesterday i got on his phone to download an app, and i seen that in his recently used apps was Tinder. I was immediately upset, and began to cry. He asked if i was alright, and i told him i was fine, and gave him a fake excuse despite the fact that i was on to him. He had never cheated on me before, so i wasn't really sure why he would now. Was he bored of me?  Is he not happy with me? I mean i wasn't absolutely sure if he even was, so i got on the app, and it was logged out, so i put in his phone number and it popped up his account. I went to his profile, and in his bio it didn't say anything about being in a relationship at the moment or anything, so i was really worried. I went through his messages and he hadn't flirted with any of them, and he had mentioned to them that he had a girlfriend and that he had no intentions of anything, but it was the fact that he was still talking to girls, and not even telling me about them. So just friends or not, he was still guilty. I was super glad to find out that he told them that he was in a relationship, and that he didn't want anything more than a friend, but like i mentioned before, he still didn't tell me. I don't really know how to talk to him about it, or to give him time to maybe tell me about it. What do i do????

Sincerely, The Concerned Girlfriend

​Dear Tinder Hearted,
Let me throw down an analogy for you. 

You go to Bass Pro and buy $3,000 worth of fishing tackle and a new $69,000 Ranger bass boat. You hook up and back it down the boat ramp-- almost to the water. The game warden stops you and asks to see your fishing license.  What will he think when you tell him, “I’m not going fishing, I’m just sitting here in my truck with everything a person needs to fish but I’m not fishing”.  

The gear/boat = the phone app
Hooking up driving to the water = his profile

Hey, if he ain’t fishing--I mean cheating-- he’s missing a dang good chance.
