I kicked my ex out of our home (joint tenancy) at the end of June, I realise it wasn't the best way to go about things but after years of toxicity, communication issues and him not taking my concerns seriously, I snapped.
He spent a while telling me I didn't want him to go but was just taking other stresses out on him (he always says this) but eventually left.
An hour later I got a text saying he was going to sleep in the garage, then he turned up at the house wanting the phone charger we share, he eventually left then sent a text telling me the Internet would be turned off "shortly" (it's in his name).
The internet wasn't ever turned off and the next week, I can't even remember how but he'd started being nicer to me. I helped him find a room to rent and he asked to stay here while he was decorated. I agreed and we ended up sharing the bed, which was hard for me as by that point I was having doubts and I kind of got a bit beggy and pathetic, he maintained that he was leaving but wanted to stay friends to see if we can develop a relationship from scratch in the future.
He moved out 4 weeks ago and only collected the majority of his work stuff from the garage a week ago. The rest of the stuff he uses less often is still in there and he has the spare garage key, as well as the car key which as he drives and I don't, he can technically use whenever (he has a van so doesn't tend to use the car, though).
He took the xbox with him when he left which although I bought it, I agreed with as he uses it more than me, and he uses my Netflix account to watch TV, which again I offered.
He's been round most days over the summer, either collecting and dropping work stuff off to my garage, driving me and my children places when needed and taking me food shopping, so he's been helpful in that way but anytime I broach anything to do with us or the future, he ignores me and we end up arguing.
2 days ago he randomly messaged asking if he could pop round for coffee while he was on a break from work, when he got here he was covered in dust from his job so wanted me to bring the coffee out to him. While I was there, I asked what was happening with getting my children to school next week; he's always done the school run as I don't drive, I've kind of hinted a few times at him carrying on until my driving test in Oct and he's never disagreed, but not outwardly agreed either (talking to him tends to be like getting blood out of a stone) and so this time, he told me he didn't want to take the children to school and back as it wasn't his job to do it any more. Then he picked up his phone and started scrolling and ignoring me, so after getting annoyed at his lack of response I went inside and he left.
I phoned him later that day and we ended up arguing as he wouldn't change his mind or see my point of view, so he hung up on me.
Then yesterday, I accidentally opened a letter that was for him. It turned out to be a next steps letter about a speeding fine he's ignored for months. Seems like it's been to court and he owes £700 so I phoned him, then when he didn't answer I sent him a pic of the letter telling him he should sort it out and he replied asking why I was opening his mail. I explained it was by accident and he basically was really off with me, I ended up telling him I'd phone the court and give them his new address if he won't deal with it as I don't want bailiffs turning up here and he accused me of "starting the threats early".
This triggered me (I have anxiety) so I phoned him a few times but he wouldn't answer, then he blocked my number.
I then decided to tell him to collect the rest of his stuff as I'd be leaving it outside the garage. He sent some nasty reply then muted me or something on Facebook so my messages don't get delivered.
Today, I noticed his van drive past my house at 9am so I sent him a nicer message on WhatsApp, just asking if we can be civil. His reply was that be was driving past to check his stuff wasn't outside.
I now think he might have changed the password that enables me to log in and pay. The account is in his name and so all forgot password links go to his email address, so I can't change the password without him helping me.
Sorry this was so long, I'm just wondering whether I've been completely unreasonable in dealing with this or whether he's also being a bit of an arse?
Part of me feels like I should change the Netflix password so he can't get access but it feels so petty and he gets angry anytime I try to assert myself, so if I did do it, I know he'd have even more reason to call me a psycho.
I desperately wanted to stay on good terms with him and prior to phoning him far too much yesterday I don't see what I've done wrong
