This is the first time doing this kind of thing but since i have no one to tell this to im just putting it here to help myself feel better. So this might sound like some everyday thing but the girl that i have cared for four years and tell everything to and viseversa has basically just stomped on my heart. I know this might sound like some cliché but she knows how much i loved her and she felt the same way but then i found out that shes seeing someonr else and she was talking to him in front of me in my bed and this just pissed me off so much i really have no idea what to do. sould i stop talking to her for a while or what???

You should do nothing. Just wait, act as a friend, she'll notice that something is weird. If she do something for it, she cares about you. If she don't, sh's not worth of your attention

Don't back away from her just stay friends (you need a lot of courage to do this). BUT only be friends.. hide your feelings and she will miss you (eventually). Give it a month or so.. if that doesn't work just move on with your life.
This is the best advice i can give you right now.

>>2 >>3 These guys have it covered. DO NOT freak out, that won't help your situation at all. You may even find it's some ploy to make you jealous~

thanks really appreciate the help
