Me and my gf have been dating for 4 months now! After a drink she becomes very flirty and dances with guys in front of my face!! Deep down it really hurts but her friends have started to notice it and makes me feel like everyone is watching me!! It really upsets my gf cause she thinks I don't trust her! But I genuinely feel like I have an issue and don't no what it is?! Can you help?!
