Help please

Ok so i love him and he loves me but we're not dating. we both agreed that we dont want anyone else and we wont do anything with another person.
i was flirting with another guy online and left the evidence on my page. i thought it was harmless, because i felt nothing for the guy i was flirting with.
however when he saw it, he got upset and now he wont answer my texts at all, he keeps ignoring me.
i apologized and told him it meant nothing and that i was truly sorry but i got nothing. it drives me bonkers that he's not speaking to me AT ALL grrr. what do i do??

Well i know i deserved it i know that my ? is what do i do now???

First what I want to know is how you can be "not dating" yet say that you only want to be with each other and won't do anything with anyone else? To him, I'm pretty sure that's as good as saying you're dating. If you wanted to get away with flirting with no consequences you shouldn't have made promises of commitment thereafter, that or specify what is or isn't applicable.

Second, what I don't understand is if you don't even have feelings for this other guy and don't plan to be with him; if you love "Fred" (decided to put a name to the face because I don't want to mix these two guys up) and only want to be with him, then why even flirt with this other guy to begin with or at all? Even though you say you're "not dating", you basically made a promise to him, like he did to you, that you only want to be with him and won't do anything with anyone else; a sign of commitment. A promise; a commitment, you broke. Be honest, where you even able to keep that promise; stay committed, to begin with? You think it was just harmless flirting and didn't mean anything; I think you're a liar. You don't flirt with someone just because, you flirt because you want the attention. In the end, it did hurt someone who trusted you. I agree with Amanda, if you can't understand what you did wrong by him then you will lose this guy and every guy that comes into your life.

All you can do now is accept the consequences that may come and to wait till he decides what to do.
