Boyfriend hiding/erasing texts?

carocarito
I have been dating my boyfriends for three years now and two months ago I happened to be looking at the time on his phone when a text pops up from a girl. I had never heard about this girl, so I opened the message and saw that he has been having a two-day long conversation with her about their jobs, cars and what boys like, etc...with a LOT of smileys...thing that he doesn't normally do. I asked him about, told him the convo was flirty and he admitted, said he was sorry, and that he was only follwing the lead of this classmate of his to not me be mean.

I thought the problem was over, until another day I saw more messages between the two, but these messages were cut, as if he erased the previous convo, again, something that he just normally does not do. He insisted nothing is going..and is calling me paranoid, but I would not be if he would just be open, and not hiding texts.

Yesterday, we were at a bar with a group of friends, and I found another text from her, from a conversation he has deleted and started at the bar...while he was with me.

I would love some guy opinions on this matter...could there be something going, why hide always erase the messages if nothing is going on? and the fact that he texted her in secret while out with me at a bar?

ps: I should also mention they are in the same classes

AND that I know trust is the base of a good relationship...but his hiding and lying does NOT help me trust him
