Input: I'll try to keep this brief as possible, but the situation is quite complicated. My thoughts are jumbled and there's a lot of backstory, so sorry. 

My boyfriend of 5 years, we'll call him Kay, dumped me about two years ago after cheating on me for a month or so, I was crushed but he got over me very quickly. January 2018, he friends me on Discord and asks if I want to be friends and says that he misses me. I missed him a lot and still loved him so I enthusiastically agreed, kind of sort of hoping he'd been dumped or something and we could rekindle something. He hadn't been dumped but seemed to really enjoy having me around again, I'm generally very kind and supportive and he needed that at that point in his life I think. 

Fastforward to November, my mother is in hospice after probably 4 or so years of stage 4 breast cancer. She was in home hospice for a while, but about midway through November she was moved to a hospice facility. My mother has been pretty much my best friend for my whole life, so obviously I'm not having a good time.

One night, Kay, unaware of my situation(I think, I don't remember clearly), messages me saying that he doesn't think his current girlfriend cares about him. I legitimately love and care for him, so I spend a few hours talking to him and going over the situation. I don't associate with his girlfriend, but I tell him it seems like he really loves her and he should try to talk it over with her instead of breaking up then and there, in spite of my wanting him back. 

Here's the inciting incident. He starts to tell me that he's sorry for the way he treated me when we were together. I wasn't perfect in our relationship by any means but I do believe he was worse in the end. Anyway, he says that if there's anything he can do to make it up to me he would promise to do his best to do it. At some point, I really forget this detail, but I told him my mother's situation. He swore up and down that he would be here for me whenever I needed him. He knew she wasn't doing well for a long time but it wasn't til this point that he knew she was basically gone mentally(Not sure if it's the drugs she's on or the brain tumors but she's gone). 

For a couple of days, he would talk to me whenever I wanted and spend lots of time with me doing things we used to. I don't know if I did something or overstepped/got too close or what, but one day it seemed like he wanted nothing to do with me. I confronted him, because I'm quite closed off with most of my friends and I was quite desperate to be around someone who really knows me, which he does. 

My interpretation of "being there for me" was to spend time with me, keep me company, talk to me, things like that. Not all the time but I didn't think every couple days or so was too much to ask. I'm not sure what his intention was in making this promise to me, I've asked him several times if he wanted to retract it, but he stands by his point of view that he has been here for me as much as he should be. 

I know that I'm very emotional in general, and especially now. I've had way too many talks about this with him because I can't just let it go. He'll still spend time with me occasionally but he seems completely emotionally closed off from me. 

Anyway, please don't feel sorry for me in judging whether or not I'm the ass hole here. I know I'm clingy and can be kind of controlling, but I legitimately don't know if my judgement of him being neglectful and callus toward me is clouded or if he just got bored of being around me again and won't just tell me and get it over with.

TL;DR My ex-boyfriend promised to comfort me and keep me company while my mother is in hospice. He seemed to get bored of "being there for me" after a couple of days and will now barely talk to me. I confront him about it pretty frequently and I've been very vocal that I believe he's being neglectful and cruel toward me.
