My friend has not been diagnosed with depression ... She might just have the kind of Debbie Downer personality that's a bit overboard at the moment. 

We meet 3 years ago at work. She would often complian about everything.. Work, the country we live in, other people etc. 

Then, her best friend left our work place, and after a few weeks of her trying to catch up with her, the friend sends her a text saying that she didn't want to have anything to do with the old work place because she had had such bad experiences there, and just cuts ties with her. She was devastated.

We become closer..best friends, tell everything to each other kind of thing. 

2 years ago she started having doubts about her relationship and complaints that she does everything her boyfriend wants and never gets what she wants. Every time we go out, day or night , he calls , insisting for her to come home.. 

1 year and 1/2 ago she meets this guy at work and ends up having a crush.. they see each other twice for coffee.. but nothing happens from there on. Then 1 year ago she meets another guy.. this was worse.. for the first couple of months they declare love for each other... But she ends up saying she will never leave her boyfriend, so ended it with the guy.. she never physical cheated because they live in different countries..but emotional cheating in my POV.

 it gets complicated. This guy is super depressed, is in therapy, had has a history of attempting suicide in the past. He's also the type that uses that to guilt people in to things. He's super in love with her, and she just wants to be friends, says they have an amazing connecting, and he's family.. so they still talk everyday.. she hides a lot of the communication from her boyfriend, because she knows it's too much to be acceptable. But since he's so depressed she seems even more  Depressed from being connected to him and enabling this friendship. 

I can't help but judge... I've told her she shouldn't keep contact with him after their involvement and because he's still In love and won't be able to get over her if they still have contact. I've only said something over hours and hours of her complaining that he cries a lot because they're not together. 

Her boyfriend might not be great.. but I don't think he deserves this.. even if they re just friends now. 
 
We used to have lunch everyday.. but I've avoided seeing her as much.. I schedule meetings at lunch time. When I do have lunch with her I'm always thinking "this time will be better, this time she will be in a good mood".. and then regret it later.

She used to have other friends, but I'm her only friend now. We used to go to breakfast Saturday morning when I was single. She's told  me she used to be happier because we would go for breakfast and have some laughs, and that now she has nothing in her life to cheer her up. She kind of made my feel guilty for her misery.. which I feel was unfair, and it's too much responsibility to be her only friend.

I can't keep scheduling meetings and giving excuses... I don't like lying.. not even white lies.. but I also can't tell her I can't deal with her, I think it would devastate her.

So I've blew her off several times by saying I want to have lunch alone, because I need some time - this is true and has happened in the past, she knows I'm introverted and need less social time and has always respected that... But I think with time she will start to feel suspicious because I'm consecutively doing it... She's already asked me if anything is wrong and said I no. Not seeing her everyday has made me so much happier... But as a friend shouldn't I be there for her? Instead of just cutting her out because she's been having a bad time? AITA?
