Frankly, yes.

Not because it's guaranteed that anything untoward is happening, moreso because she now knows that this is fundamentally a trust issue and rather than address it she seems to have shrugged it off.

If the tables were turned here, would you not go the extra mile to ensure that she knew the long and short of the texts?

Sure, she denies it. Fair enough. But she has done nothing to ease your doubts. That's what makes my internal alarm bell ring.

Last night, I caught her lying to me.  I saw her texting one of these guys, so I asked her about it.  She denied that she was texting them.  So, I asked to see her phone and sure enough, she had texted one of them.

I still don't think she's cheating on me, but I don't understand why she's hiding this from me.

Why are you denying the obvious? Do you think if she was into you she would be acting this way? She is playing the field so don't be surprised if one day she says goodbye when someone comes along that is  "the one".

I was in a similar situation, and the best advice I can give you is trust your gut. We tend to be very intuitive when we listen to the signs.

If you have confronted her about these conversations, and she has told you they are just friends and nothing to worry about, you have two options.

1. You trust her. Has she lied to you before? Has she been flirtatious with other guys before? If you do not have any explicit signs that she is lying to you, you are going to push her away with your distrust. Your second option is:
2. End the relationship. Once you stop trusting someone, it is difficult to get that back. If she is showing red flags, it is up to you decide whether or not they are deal breakers.

Simply put, if you cannot trust your significant other, it is best to end it before it progresses and causes you both unnecessary pain. I know it is hard to put your trust in someone else, but it is imperative to make your relationship work.

Best of luck.

This is an annoying situation but it is something you need to take control of. Simply talk with her and tell her how you feel about her texting other guys. If it really bothers you, tell her that. Tell her you just feel uncomfortable because she never mentions the guys to you.

Shes hiding somthing... ask her if she told the guy texting her that you are her boyfriend and not try to keep asking her to go out
