Allow me to condense 1 1/2 years of history into a few paragraphs.
I met Brittni in July of 2009. I was living with my parents at the time and she hers. We had gone out on a date in that month and things moved quickly from there. In September, we had moved out together. Her daughter, Lyla--5 months old at the time--came with us. I went from 0 to 60 in a matter of days, raising a child who was not my own and living the life of a married man. I'd say I adapted pretty quickly. But I made a terribly stupid decision that only time and experience could allow me to see.
Why was this a dumb decision? Because Brittni was a cheater.
The first time she cheated on me was in October of 2009--Halloween, to be exact. Times were tough. Really tough. I was out of work and we were staying at her parents' house for a few weeks. Brittni was working as a secretary at a local company called TLI. She became good friends with one of the computer technicians named Joey. I had always suspected that something was going on between them. She would come home, go to her room, and immediately call him. I summoned up the gumption one night to look through her text messages. Low of me, no doubt, but my suspicions were confirmed by several inappropriate text messages that he had sent her. I confronted her on this one night and she was pretty much speechless. I naively thought that I had put an end to their behavior by confronting her on it. Wrong.
Joey had invited us to a party at his house for Halloween. I wanted badly to go--I was 20 and there would be alcohol. So we went, and this was a grave mistake. Long story short, Brittni and Joey had sex in his bathroom.
She told me about it a few nights later as we were laying in bed. There were tears, apologies, etc. I didn't leave her, though. I forgave her for what she did in the hopes that my mercy and love would show her the error of her ways. Wrong again.
She cheated on me again with my brother while I was at work. Twice, to be exact. But I still wouldn't leave her.
Many of you reading this may wonder why I continued to let her treat me this way, especially after I had forgiven her. It's the same reasoning that an abused wife uses when staying with her abusive husband. She doesn't know/can't imagine a life outside of her marriage, and also believes that she can change him for the better. I certainly couldn't imagine leaving the life that I had made with Brittni and Lyla. Youthful naivete caused me to think that I could perhaps change her.
I've stayed with her since this last incident. Something about our relationship had died, though. I'm irritated all the time. I don't trust her anymore. I don't love her like I used to. I can't. At the same time, my parents love seeing Lyla. They view her as their own. If I left Brittni--and what a tantalizing prospect that has become!--they would be deprived of seeing her, which would devastate them.
I am so lost.
