Bit of background, me and DP have been together approx 6 years. Have a toddler DS together, live together but unmarried. House we are living in is rented from my family.
Me and DP have been having some serious issues the past few months. He broke my trust in a big way, and then instead of just apologising he got quite manipulative and tried to turn the situation round on me. I wasn't having that and told him it was over between us. He managed to convince me to give it one more go and for the sake of our DS I agreed.
So things have been a bit awkward since then but slowly getting back to normal. Until yesterday, I got some bad news that a close friend is very sick. The diagnosis is life changing and potentially fatal (they are currently awaiting more results to see how bad it is) obviously this was extremely upsetting, and I really just needed my DP to support me deal with this so that I in turn could be there for my friend. However, he was just useless. Was not supportive at all, and just made everything harder as I was having to deal with his shitty behaviour whilst also trying to process this information about my friend. We argued about this yesterday with no resolution.
He had plans to meet up with his ex today (they are still friends and meet up every few months for a catch up. I don't like it but not the hill I was willing to die on) he was meant to take DS with him so that I could have a day to myself to get the house cleaned and tidied. He woke up this morning and asked if I really needed him to take DS with him - you know the way people seem like they're giving you the choice but they're really not. So he's left DS here, and now I'm just sat here crying at how he could be such an asshole to 1) abandon me to hang out with his ex when I'm struggling with things and 2) not even take DS with him like he said he would to make my load a little easier.
I just feel so alone, like I have no support from him and I honestly am feeling like I could just end it. I know if I speak to him about this he will make out I'm being massively unreasonable and he's entitled to hang out with his friends etc so AIBU?
