Okay guys... I asked him about it. As you know it's been really bothering me and I couldn't keep it in any longer. I made sure I wasn't accusing him and I'm SO glad I told him as it's a big worry off my shoulders and I feel so much better. He was really nice about it too, he just seemed embarrassed. This is what he said:

oh my gosh you did??

im so sorry

you know what im like

i feel bad easily

hurting her made me feel like absolute s***

i just wanted to let her know how bad i felt and how sorry i am

i dont want her to think of me as some d***
