I thought i had something really good going for me because this girl made me feel truly happy for the first time in years. So this girl I've been with decides to lie to me for over 2 weeks about seeing a kid who i once considered to be a good friend of mine. She has no clue i know yet. I just found out earlier today after she told me that she couldn't go out tonight because her mom wanted her to clean the entire house. Considering that she lives in a rather strict household i believed her. So i offered to drive over and help her clean but she tells me her mom said that she can't have anyone over. As soon as i got off the phone with her, my best friend calls me and tells me that this girl has been lying to me. And that she has been seeing this other kid all week. And that the kid was over at her house right now. She was the first girl i cared about and my last chance at happiness till i moved away. Should i keep playing dumb, or tell her i know everything that has been going on...I thought i would be angry but I'm just severely depressed.
