I dated a girl for a month who bought me gifts, took me out to dinner, we spent New Years Eve together, I watched her dog for her when she went out of town. She would send me pictures of her kids, we hung out 2 to 3 times per week and then one day out of the blue she was done.
Come to find out she had an on again off again BF and they had recently broke up. I was her man during the break up period.
