This is what happened. My boyfriend and I were together for about 4 months. Everything was going great we always hung out and texted and he was really sweet. Until one night I decided to make a stupid decision and test him. I used my cousin's phone to text him and ask if they could secretly date without me or anyone else knowing. He said yes. Later on, the night we tried talking he told me it was a set up he felt bad for her because she didn't have many friends and everyone was mean to her. The second thing he told me was he was going to tell me later about the whole thing so I could embarrass her and yell at her. He says it was never real and he swears it was just a setup. It has been about 1 week and he has been trying really hard to get me back and I just don't know what to do, I need help!
