<human>: Condense the text into a few key points

Our relationship was shitty at the start; I grew very dependent on him whilst he spent more time with his friends than with me, which obviously caused massive clashes and arguments. I felt unwanted and he felt trapped. It culminated in a cycle of him attempting to break up with me and then changing his mind repeatedly. This went on for about a year and a half. 

Suddenly, fuck knows how, everything changed. He hasn't mentioned breaking up in a year and a half (we've been together three years now). He ditched friends who were assholes to me and now dedicates his free time to me, entirely. He is literally everything I wanted him to be in the beginning; he prioritises me, makes fun plans with me regularly, treats me, compliments me, makes at least a small effort to make me happy on a daily basis. He's awesome and I sincerely love him. 

The problem? I'm depressed. I've always had some issues with low mood/anxiety/serious self-imagine issues but never as bad as this. My Dad told me he was leaving my Mum just before Christmas and now they're getting divorced. I lost a close friend around the same time. I lost my job after Christmas. 

All of this stuff had a huge impact on me and I'm just really sad now. I have no motivation to do literally anything, I don't enjoy being around people much and I've lost all interest in stuff I used to enjoy (including sex). I feel guilty that I feel so sad when I have such a lovely boyfriend who has been so wonderful and supportive. I feel like I can't enjoy myself around him or entertain him when I can't even entertain myself. 

I've been slowly isolating myself from him, cancelling meet ups or leaving early or ignoring his texts. I don't want to push my shitty feelings onto him and have him begin to resent me for being sad and boring. I've subtley hinted that he may be better off without me and I think he's starting to worry that I'm going to leave him.

Maybe I should for his sake?
<bot>: Boyfriend used to be shit but is now awesome. I'm depressed and slowly becoming the shit one. Should I put him out of his inevitable misery and end the relationship before I make him hate me?
