Yeah, I did... for a really fucking complicated and like all reasons - immature reason... which was that She had basically cheated on me, then left me for the guy, then I sorta stupidly took her back when he didn't want her for anything else than just a fuck'n'go,
Thing is, she was still very distraught over the guy who she cheated on me with, and subsequently left me for... for like the next few months. Which was pretty god damn obnoxious.
I felt wronged basically the whole time, and so fucking used. But I wanted to be with her so bad I didn't really care I guess.
So I cheated on her. Because she didn't seem to really WANT to be with me, and seemingly was only was with me because the other guy didn't want her. But I also cared about her so much, that I wanted her to be happy, and me being in her life made her happy. On top of that, she was going through some shitty stuff. If I had left her, it would have just stacked more shit on the pile of 'woe is me' that she was going through at the time I suppose.
Do I regret it? Kinda... yeah... but now after writing this, I guess if there was ever a position where cheating was morally 'okay' in my brain, this was it.
Pretty complicated and stupid situation, really.
