Me (28 year old female) and my partner (27 year old female) have been together for 6 years. She got diagnosed with ADD a few months ago and began medicine. A little background on us. As soon as we moved in together it was clear that something was different, she wasn't able to concentrate, get things done around the house and i pretty much was left to handle all the house hold duties. Me being a full time student and her working full time, I tried not to complain so much since I had a little more free time than her. It began to bug me and of course we started the cycle of me resenting her and mentally checking out of the relationship, following with her some what doing the same. About a month ago we got into an argument and I threatened to leave, she cried and said she didn't want to lose me and wanted to try therapy if I agreed. I told her if she made the appointment then I would go. She never did. Two weeks ago we had got into a fight because she came back home from her business trip acting very different. The same weekend of her business trip was the time when I had an AH HA moment, realizing I did want to try, therapy, rekindling the romance, and anything else to keep our relationship afloat. When she returned from the business trip acting different I confronted her about it. She denied anything was wrong, I gave her multiplet times to tell the truth and just be honest. A few days past and I just asked her " are you cheating on me?". She said no, then I told her that I wasn't stupid I know something going on. She then said she heavily flirted with someone while at the business event to the point where they felt comfortable enough to ask her out on a date. She said she realized it was wrong and shut them down and ended contact. I cried hard because one thing we had in our relationship was trust 100% trust and that was broken. I said I was leaving, when really I walked miles just to get my thoughts together. When returning home she called me to tell me she had left since I left and that she thought we needed some time apart or separation. I love her and she is everything I've ever wanted in a partner. I agree that all these years of fighting, we both deserve a little space but I can't help but feel she just wants to explore these new feelings. A week before she loved me and wanted to work things out, now after her flirt session she wants space and blames me entirely for not attending to her needs. What do I do?? To me, 6 years is a marriage, and I don't want to lose my marriage. Any advice???
