Sorry????

I really ain't a dumbass! I knew she did it with her bf but she is trying to treat it as nothing happen last night with her bf.

How can she treat it as nothing had happen and still wanna go out with me and get intimate with me? How is it that she is still able to kiss me when she was having a great time with her bf making out and kissing and sexing and all?

I really feel like I am so used.. I can't accept that she is alright with it. I am struggling here and all she can tell me is sorry.

What's the point of saying sorry??? Argh!!!
