Well I think 'breaks' in a relationship will cause more problems because trust issues will come about 'have they slept with someone else' is their someone else they like. I think you need to sit down and talk, listen about why the relationship is the way it is. Talk like adults and do not be tit for tat as this just ends in a war zone. Let you gf no how you feel, explain how this feels to you. Ask yourself this. Are you spending to much time together? Do you go out and spend time with your friends? Do you keep your spark in the relationship, going out for meals, cinema or maybe a weekend away? You boh need social lives outside the relationship you cant live in each others pockets or if you do socialize outside your relationship how does your partner feel about your friends? Is their certain things you do that irrtate her? Have you listened to why she feels like this. Sometimes girls will beat around the bush and not get straight to the point over fear of upset. If this doesnt work then maybe its not meant to be but a relationship is 2 way
