We broke up as she’s not ready for a relationship and I told her I’d wait for her for when she’s ready. After some time we got into a big argument and said we didn’t want to see each other anymore and stay away and never talk again. We’ve since contacted each other and said we need a bit more space but will talk and get together soon. Problem is is that while we were fighting, I talked to other girls. I wasn’t quite over her yet, but I was trying to move on, to no avail. Some of the girls wanted to meet up and fuck or go on dates. I didn’t feel like it was right and didn’t do it. Should I tell her that it happened and I chose her overall? Or should I just tell her I was faithful and never once thought of sleeping with someone else? Or should I not mention it at all?
