Thank you everyone for your replies so far, they have been very interesting and thought provoking.
I do want to clear something up though, i guess my first post here wasn't entirely clear. I blame myself as i did have to type it up quickly. I have no interest in getting back with my ex. And as for gaining her respect, part of me would like that, just as i like others to respect me to. I gave that example to show because we aren't in regular contact anymore i have little experience with how to act around a girl who did such a thing. I don't wish to burn bridges as that really seems to me to be to drastic a solution, and as we both were aware of how difficult long distance was, we still remained friendly with one another afterwards. And of course i hate cutting myself off from possible future options, whatever they may be. I prefer to turn relationships back into friendships, and so far i can do that. Except i've never really tested myself in this particular situation.
When people have shown me disrespect in the past i have cut them out of my life, i've never had the time to deal with people like that, and there are always plenty of new people to meet. But doing that i've found really does limit options, and so i see it as too drastic these days, so it will always remain the last and final option. And it was partly through reading some threads on here of people cheating that reminded me of my ex, and the fact i have very little idea of how i'd act to keep from making the girl see me as being some kind of walk over, an idiot, etc if i was to still keep intouch and be friendly.
RedPill, what you've said makes sense, and to be honest, is what i partly do when a relationship ends. My thoughts about the girl and wanting to be with her drop, and i only seem to think about her in terms of friendship, if at all. It has always made moving on with my life a lot easier, so easy that the cutting people out of my life option is the most natural thing for me to do. I don't want to be limited though. And what you said helps me to work out ways in which i could act, which are natural to me and not forced. Anything else you could add though would be appreciated a lot.
ethnomethodologist, yes, what you said is what follows with my understanding. The not blowing up and getting insecure part that is. Add to that what SoCalMike said, about not acting mean, being polite, etc, that helps to. That should help me come up with some more ideas.
I will add before i finish this, i do believe somewhat what Wyldfire said way up there. Eventually one of us was going to be unfaithful, and neither of us were blind to that. It was a risk we both knew was worth it, and our time together was great. Personally i expected her to cheat after 4 or so months, it surprised me when we lasted 16. So while some of you may feel that what Wyldfire said was coming up with an excuse to defend my ex, there was some truth in it. Even an excuse leads to the truth if you want to follow it. So i don't see a problem with that... only problem i can see is if you were to accept the excuse and do nothing about it.
And Wyldfire, JonJack, thank you both for providing a different point of view for what you thought was my situation. One taking into account her feelings. That i see so little these days, i hope to definately read more of your posts in the future, and to hear more of your opinions and views on what i write.
Oh, and definately one last thing... STR8UP, Wyldfire, any problems you have with one another please take it elsewhere. While your discussions have added quite a lot of useful information, i don't want fights.
Again thanks, and any more replies anyone wants to make please do. Infact now i think about it, how about some ideas of how to act after the cheating, that would really make a girl look down on you. Make her just think that you aren't worth sh*t and walk away.
