Long story short.

I (16m) was at a party, I was stupid and kissed an other girl. A few days later it came out and my gf (16f) was devastated, she was crying for weeks and I felt so stupid and guilty. We almost broke up but we decided, no matter what, we will continue to keep this relationship alive.

Fast forward, her sister (23f) also found out about this and she wanted a conversation with me. We were talking for almost an hour alone which was pretty weird, she told me that she will only allow our relationship to continue if she can track my location. I agreed.

We both also agreed to keep this between us.

Is it had if I don’t tell my gf about this ? AITAH?
