I recently split with my girlfriend of almost 2 years. We are both mid 30's. Our relationship was fine up until the last 2 months when she started blowing hot and cold. I had asked her if something was wrong but she said she was just stressed with work. She ended the relationship suddenly stating that she didn't miss me anymore and that she wasn't happy anymore. I'm convinced that she had been thinking about breaking for the last two months which would explain her being hot and cold. I'm 90% certain there wasn't another man involved. What I can't understand is that the last time I saw her as she left my house she said "I love you loads" and a few days before the breakup she texted me one morning saying "good morning, love you". My question is why did she tell me she loved me and pretend everything was ok when she was obviously planning on splitting up with me?
