Should I keep going out with someone who has started really annoying me?!?

Start by sitting down and talking to him, explain how his reactions are making you feel and that you need some time to yourself as well as with him. If he doesn't give you space or back off a bit and is still annoying you I would end it. Its pointless carrying a relationship regardless of whether you are scared you will never find someone if he annoys you. You will never be truly happy. Hope this helped and good luck XxX
