Relationship Break, help.

[Robert28]

Okay, so. my girlfriend and I have been going out for 13 months and we ahve been argueing alot. We get along more than we argue, but we just get upset with eachother over nothing sometimes. So we decided to take a break for 3 weeks and see how things turn out. It's only been a few days and I'm taking this alot harder than I thought I would. I really miss her and want her back but she's determined to wait out the 3 weeks. I'm not nagging or bugging her to come back becuase I know that won't help at all. We are going to have a little conversation everyother day just to stay in touch with eachother. She also said that she feels like she can't hangout with her friends (she has more guy friends than girl) because they don't feel comfortable hanging out if she's in a relationship. I know that they say a break can be really healthy and good for a relationship. I just want to know if I should fear anything and if it really will pay off. I can't stop thniking about her and really want her back, all help is greatly appreciated. Thanks.
