i am in need of some advice... i have been dating this girl for about 7 months now... and latley she has been getting on my nerves... really bad. she has been pretty bitchy to me. and when i try and talk to her about it... she claims i am the one being mean. and thats why she is being mean. i really care about her. but i dont know if i can continue to put up with her shit. like one day... out of no where she decided to tell me that she wanted to take a break. and the next morning she called saying how she made a big mistake. i think that there might be another dude involved. cause her ex has been calling her alot... and they were all in love and stuff. but i dont know. i hate when relationships get like this.
