Haven't talked with my girlfriend for almost 2 weeks. is she waiting for me or not interested?

Anonymous
it has been 2 weeks since i texted her. before that i was always initiating contact. she was replying lazy so i stopped contacting her. im the last one messaging her. i meet with her one week ago tho. so we can say i we havn't talked for a week.
why haven't i talked to her?
1. i'm the only one initiating contact and she replies late. so she kills my mood basically ( i don't know why girls think they are being hard to get when she replies late , it totally kills the mood and affection and forget what i wanted to tell you.)

2. i saw her talking to another guy last week after i left her and she know i saw her.. so i suspect she maybe cheating one me
( my friend told me he saw her with him 2 months ago and i didn't believe him and trusted her enough not to ask her. so yeah it paid off :/

3. i didn't want to ask her right away in order not to act out of emotions and until i can think clearly of the whole situation.

with that being said. why do you think she didn't contact me even though i have asking and contacting her? i wish i could meet with her to ask her what is going on but i cannot see her until one week. so it has to be texting.
i have to options :
1. continue ignoring her till she messages if she is still interested.
2. contact her normally like nothing happened. yesterday our results came out. so i can ask her about that.
