I've got a dilemma. My partner of 3.8 years admitted that she had a fling with one of her male work colleagues (has a girlfriend) during our temporary separation. She spent a lot of time together like as if they were dating including lunches, dinner, went to an amusement park, and staying the night at his apartment.
We have been living together for over a year and have had more of an argumentative relationship rather than a happy relationship living under the same roof. I wanted to leave her, but she was still deeply in love with me and said instead it would be our "time apart" and give ourselves space. I guess I would say that she loves me more than I would love her. So we took 1.5 months apart even though we still lived under the same roof.
For the first 2 weeks she kept on confronting me that she loves me and to try to work it out. But I still didn't want to continue our relationship and put up a cold wall to block her out (I could clearly tell she was saddened that I didn’t want her back). After that initial 2 week period I suspected changes in her and found a shock discovery. Her perfume changed, she started being happy again, dressed more sexier than usual, stayed at a "friends" place overnight, worked longer hours and worked in the weekends. Then I discovered condoms in her sleep over bag. I did not confront her because I was in denial.
I ended up giving her a second chance and we got back together to try work things out without me knowing what happened. She was very edgy about me going near her mobile and laptop which added to the suspicion. One month later she made the confession during a heated argument. She said it was ok because we weren't together. The work colleague has now been engaged to his girlfriend and has been posted overseas. She said they only slept with him once and all other times she didn’t do anything.
She says to me that she’ll never do it again and states that she never liked him but he was there to help her through sadness of me not wanting her and he was there to fill my gap. She does seem like she sincerely loves me so much as I am her first true love. I do want our relationship to work because she shows me so much love, but I’m riddled with the fact that she has been intimate with someone else, not to mention my trust for her is gone.
What do you think?
Does she deserve a second chance since she truthfully confessed everything that happened?
Should I stay or should I go?
