How I Keep Myself On Track

I've been able to keep myself on track by asking myself, "Is this really what I want?" I stopped talking to other guys when I realized I was only doing it because he was talking to other girls.  I don't really want to talk to other guys.  I love flirting but that's it.  The things my husband does should not effect the things I do.  I don't want to find myself in another situation where I talk myself into a fog.  At the same time, I feel so crummy I want to let loose and do reckless things.  I know those are temporary feelings.  I'll regret those things if I did do it.  
I know what I want.  I've wanted it since before I met my husband.  Whatever is going on in my relationship is not what I wanted.  I wanted to give my all to 1 man.  If it doesn't work with my husband, I don't want to start another relationship. EVER.  I'll be a bachelorette for the rest of my life.  I'll be celibate too.  
I don't want to give up on my husband and I definitely don't want to give up on myself.
