I've been in a relationship for two years and it's been difficult at times. I'm unsure if I want to spend the rest of my life with him but am aware I'm struggling to think straight as I'm depressed. I need some time to think things through and be alone which he doesn't accept. I've tried to break up a couple of times but always go back to him ... I don't know why. Is it acceptable at all to break up with him by text if its the only way I can see it through because if I see him I think I'll crumble. I think it'll be better for me not to be with him because a lot of the time being with him makes me feel more down than ever.
