My girlfriend and I've been dating for 2.5 years. In the past few months she has started getting really close to a make friend of hers and I'm feeling very jealous because of it. Recently I brought it up to her out of frustration but she said that she was hurt that I doubted her commitment. I love my girlfriend very much and she's virtually the centre of my universe so I'm extremely scared of losing her, I stay up at night thinking about it and my energy has dropped down noticeably too. Can anyone help?
