Dear Jade23~
Welcome here to the Forum.
After being in a close relationship for 5 years it will have come as a trumentous shock to hear your partner wishes to separate - particularly if there have been no waning signs.
Apart from the greif and loss it leaves you in a position of wondering if the break-up is genuine , something that sadly does happen, or if in fact it is caused by some form of mental condition.
OK, if your instinct is right and he has been suffering from depression you have already done the single most important thing you can, getting him to professional help.
I found I could never make myself better on my own, it needed proper treatment, which eventually restored me to something like my former self.
Depression changes a persons thinking, and in my case left me not knowing if I loved anyone, or even if I was capable of love at all. I could not understand my own actions, it was like I was an observer.
In that condition logic and explanations, or appeals, are not likely to be of any use. My partner tried her hardest, and firstly had to overcome the feeling my behavior was at least partly her fault -something it took a doctor to explain were symptoms and not her at all.
From then on it was juggling act, walking on eggshells and not expecting me to be consistent.
At the same time I was feeling very guilty about putting her though al this, thinking it was my fault -when in fact it was the depression. That may be why your partner wanted to break it off.
This is all based on the guess it is depression causing the parting. In my own case I both wanted to be on my own as my brain was so full of depressive thoughts I could not deal with anything else, but at the same time found my wife's constancy was a great comfort.
How to manage both of those I'm not sure, perhaps trying to do an activity you have both enjoyed in the past, and not discussing the current situation, might be a help.
Please let us know how you get on
