I've been living together with my fiancé now for 8 years, been engaged to her for 3 years. We just moved into our new home 2 months ago and a guy friend of hers from years ago has been coming around . He helped us move and he became my friend too now. At least I think he is.

What bothers me is that they text all day and night. I even caught her in a lie saying she was going out to dinner with her daughter, and I happen to follow her, and she was with her friend instead.

So I confronted her and she said they're only friends just going out for 1 drink then coming home. And I had told her weeks before this happened that he comes over too much. So I for gave her, but they still text all day, and night. What should I do?

She lied to you and what makes you think she won't do it again? If it were me, most if not all of the trust would be gone. In a case like this, how long you've been together is completely irrelevant. All that matters is the trust, communication and honesty and right now, you have none of that.

You need to decide what you want. Do you want to live the rest of your life wondering if she's really where she says she is?

If she was caught in a lie then she has something to hide... you already excepted the first lie... if you want to find out what's going on, do something out of the ordinary... for example, if you are to be at work take a personal day etc and come home early... pretend to go to work and come home early... just do a little homework and you will find out the truth.

She lied a year ago - and the OP hasn't been back.
