Hi PrincessxKitty - It sounds like you and this guy have different ideas about where you want to be in life right now. To be honest if he wants to be exclusive is this not the same as being in a relationship? Why is he so against having you as a girlfriend? if he's openly said he is commitment phobic that would send alarm bells ringing for me - if he's been this way for sometime is it likely he's going to change? On the other hand if you've been together six months and have a good thing going perhaps you need to ask yourself why its such a big deal if you're not 'technically' in a relationship. Either way something has to give - this subject will only fester so before everything comes to blows i would try and establish properly why he is so against this idea - perhaps he's been very hurt in past relationships and is building up his own wall so to speak. If you feel you absolutely must officially be someones girlfriend then perhaps its best to get out of this relationship now so that you both save each other a lot of hurt. I would wait and see how things progress though - perhaps in time he will feel more comfortable? It has after all been six months so maybe its a little soon for him? I hope this works out positively for you, all the best.
