Long Term Girlfriend has Workplace Fling
Pretty sobering thought that I am at a point in my relationship where I would turn to a message board for help, but any thoughtful responses are greatly appreciated!
Here's the situation in a nutshell. I've been dating my current girlfriend for 6 1/2 years. I'm 30, she's 28 and we've lived together for over 3 years. I'd say up to this point our relationship has been pretty typical, had some problems but have always been able to overcome them. Late last year I had the work opportunity of a lifetime, but it required me to move across country for 4 months, with limited opportunity for visiting home. We talked about this, and my girlfriend was in total support of the move and we just kept saying "after 6 years together we'll make this work". Well the four months came and went and literally 3 days before I move back she calls to tell me she is concerned about our future together and is basically breaking it off with me... over the phone. I tell her we at least need to see each other and talk things through, and she agrees. Well, I've been back home now nearly a month, we've really been communicating well, and have pretty much dealt with our future together and if it is still aligned with one another. Then about a week ago the bomb gets dropped on me that she has been seeing a guy at work while I was gone. Nothing serious she tells me, but they had gone out on a couple dates, individually and as a couple... dinner, movies, concerts, etc. This guy is twice her age (57), and she tells me she really just enjoyed the attention of a man while I was gone, and that there is nothing going on between them anymore. My problem is that during our "coming clean" conversation I caught her in a couple lies, nothing big, but enough to get me thinking about how truthful she is being to me about their relationship. I prefaced this entire conversation with "you need to be honest with me right now so I can process what has happened, and try to work through it...you won't hurt my feelings unless you lie to me about something"... and she still lied. So here is my problem... she tells me nothing more happened between them than just friendship, and some dates as friends. I don't think they had sex, but I am 100% sure they did more than just go out and shake hands after the date was over. I know she is point blank lying to me about what happened between them. Truth and trust has NEVER been an issue in our relationship, and I know until this point she has been 100% faithful to me, and I to her. What makes it worse is that she see's this guy everyday at work, they work in the same office and interact numerous times through the day.
This is driving me nuts... I can't let it go that she did this, and then lied to me. I even told her she had a chance to come clean and tell me everything and make things right between us, but once I caught her lying about small stuff it made is so I don't trust her to tell me the truth about the important stuff.
This all came to a head in the last couple days. She tells me she feels awful, and gave in to a momentary weakness, made a bad decision, and feels as though she has ruined things between us. She says she is fully committed to our relationship, and getting my trust back, and that she has never loved me more.
Do I press it to get the "whole truth"? Do I trust anything she is telling me? Do I let it go that she lied about some aspects of their relationship, but still trust what she is telling me about us moving forward and that they are in the past?
Thanks to anybody who took the time to read this and respond, any insight will certainly help me sort this out.
