well id like to start off by saying that the girl im in a realtionship is to hard to understand sometimes. i met her at a friends house. she gets to me sometimes, ive been dateing her for sevrial months now. my concern is she has alout of guy friends, which does not bother me. But the problem is they always walk over her, but yet she still wants to be friends with all her x-boyfriends. one thing that makes me diferent from her is when i was in high school which was a couple of years ago i was a very quiet person. i never talked to anybody at school. she was very popular in school and i think its starnge she would wanna date someone who is so unpoplar. well any way to cut to the chase, im always scared to stand up to her, everyone else does but im to afraid to, im scared she will say some hurtful things to me or blow up at me. I wonder if im not nice enough to her! im always buyiing things for her. every week im getting her nice things, but i feel like im doing something wrong everyday to make her mad. if anyone has ever felt this way, or if someone can tell me how to deal with this problem.
