<human>: So, where to begin. This might be long.

Me: 32 male
Maria: 39 female

Met Maria a year and a half ago. She got me out of rut. Maria is the hottest person I've ever seen, I'm a 6, she's a 10. I'm realistic, I'm not putting myself down. And I'm a very confident guy. 

We have been together just over a year. Things are generally dandy. 

She has two friends, among others. 1 ex boyfriend, 1 ex friend with benefits. 

She hangs out with them once in a while, and refuses to introduce me. Says that the ex boyfriend is just not ready to meet me. Says that he was her only friend she had for many years so she cannot forget about him; they must remain friends. I have a hard time NOT seeing her perspective; she's not wrong. Plus the guy actually seems like a nice dude. But maybe I'm being too trusting. 

The ex friend with benefits: she normally tells me she hung out with him. Have caught her (unintentionally caught, have not confronted, don't know how or if there is a need) via text message indicating that they hung out, but she didn't tell me about this instance. This instance was also at 2 AM. The 2am thing bothers me, which is why I bring it up.  No actual evidence of anything else though. 

Both men definitely still like or even love her. 

I generally trust this woman. She tells me she loves me, talks marriage, I know her family well, her family knows me. 

I am having issues dealing with this. It keeps me up at night. What do I do reddit? Do I ask her what is going on, if anything happened? If so, how?

Do I just up and leave? Right back to my rut :-/ Rut is because I work like 14 hour days, no time for friends or much of any social life. But that's another subreddit issue. 

Do I continue because I'm paranoid and am just turning into a controlling asshole?

Throwaway because.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: girlfriend if a year hangs out with ex and ex fwb. Caught her not telling me about one hangout instance. What do reddit?
