<human>: Can you succinctly summarize the text in 1-3 sentences?

For the last couple years, I have been suffering of major depressive disorder. It got especially serious this year (I've been hospitalized a handful of times) and this took a heavy toll on my relationship. I didn't feel it was fair for my girlfriend to have to deal with these issues, so we discussed it and decided that the best thing to do would be to take a break from the relationship.

This didn't come without it's rocky bits. We had been together for over a year, and this was the first serious relationship either of us had been in. After getting into a fight about one of our mutual friends, I got very unhappy and blocked her on Facebook Messenger. After a couple days I undid it and it seemed like things came back to normal. We got into a couple more fights, but that settled out and it's been over a month.

She's been at camp in another continent, but we've been chatting/etc. when our timezones and sleep cycles align. We actually began chatting a lot and it felt like we finally found an equilibrium where we could still be good friends without the romantic context. But then, out of the blue she started totally ignoring everything I sent her or, at best, replying curtly. I don't know anything I might have done to upset her — the last thing I sent her before she started ignoring me was "Wanna hear a joke?" to which she didn't respond — but I'm really unhappy that she doesn't want to talk with me because, even though we aren't romantically involved anymore, I still really like her as a person and want to be close with her.

Thank you all so much.
<bot>: After our breakup and a couple fights, things seemed normal between my ex and me, but she started ignoring me out of the blue. How should I take this and is there anything I should do?
