so if you didnt want to sleep with this teacher why talk to her? personally i think you liked getting her dirty text messages cause you liked feeling like someone other than ur girl wanted you. if you would of just been honest with ur girl from the get go she wouldnt of reacted the way she did. since you hid from her that this teacher wanted the cawk then she probably feels like theres more things you havent been honest with her about. usually if you feel like you cant be honest with someone then there is something you are hiding and feel guilty about.
my girl had a guy friend at work that when they started working together they were just friends. we all used to hang out, things were cool. well like most guys you want to **** all ur friends that are girls at one point or another and one day after work he made a pass at her, she declined, then he would hit on her at work and what not. she neglected to tell me this stuff was going on. well i noticed she stopped talking to him and we all stopped hanging out and i found out from a third party all this stuff had happened. when he hit on her had she told me when it happened i wouldnt of gave two shits, i understand im a guy. you stare at a set of ***** all day, everyday and eventually you wanna see em, i get it haha what pissed me off is that since she didnt tell me it made me wonder what she had to hide, if she wasnt being totally honest with me. that, and a couple other little lies (nothing major just stupid shit she kept from me cause she thought id get mad) caused major problems with us and we went through some shit for a couple months. in fact theres a thread about it haha.
moral of the story stop looking for other girls to boost your ego and stay honest with ur girl. ur relationship will be much smoother if you both trust each other. give her space, maybe tomorrow sometime send her a text or something apologizing and telling her you want to talk. shell come around.
