<human>: So, I dont really know how to right this, so please bare with me!

I'm a weak person mentally. I am depressed and my girlfriend knows that. I have broken up with her once before, because of the depression itself, and i told her that, so she worked on getting me better so we could get back together. 

Its been about 8 months since we got back together. I'm a real mess about my stance on our relationship. We fight, argue disagree, whatever you want to call it, All of the time. 

Its happening so much lately that we have "Broken up" in the middle of a fight. But we never do actually break up. This all sounds very childish i know, and i feel as though it genuinely is. But I do legitimately love this girl, and she loves me.

As most of my friends and parents have said, we should break up, its not healthy for either of us. But thats the tricky part, im mentally weak, depressed and just can't do it. I don't have the confidence to talk to other women, I don't have the confidence to go out because i'll see her with other boys and I couldn't deal with that. I don't have the confidence to say to a girl, "Hello, how are you?" Let alone, "Can i buy you a drink?" Or something along those lines. 

I still love the girl i am with, but i don't see a future with her. I also feel like i want to fall in love all over again. Im a...Well i use to be, a real romantic, i wanted to message a girl every morning a nice wake up message, Take them out for dinner to a fancy restaurant and open all the doors for them. 

Basically i dont know what to do, If i stay with her, the situation could get worse, or it could get a lot better. If i leave her, i will probably spiral into deep depression and ruin my life by doing something incredibly stupid. 

I thankyou all in advance for your responses.

Can you condense the text into a few key points?
