I just wrote out a super long explanation but deleted it and will write points which I think are pertinent to my question. 

We are both in college, been together for 2 years.

He is on medication and going to therapy - its not really working.

He gets the worst depressive episodes when he is struggling with college assignments. 

His depression is genetic and he doesn’t really understand the root of it (if there is any apart from genetics).

When he is depressed he locks himself in and doesn’t let me talk to him much, I also feel really neglected during this time but feel it’s inappropriate to mention it to him as he’s clearly having a harder time.

I love him so much but honestly its quite draining to try to live my own life and look after someone in this state. 

He has told me that he wants to leave me because he will ultimately be a huge burden on my life - this broke my heart but has had me thinking about it more deeply.

I do see a future with him when he’s healthy and we are both so great together apart from this. Sometimes I also feel I am one of the main people keeping him together.

Am I the asshole for even considering this?
