I kicked my boyfriend out my house…did I make the right decision?

[Electra]

We have been on and off for over a year. We were broken up at new years but I sent him a message saying Happy New Year. He rang me right after and told me to go see him. of course he was drunk when I turned up to his house as usual and thats the only times he wants to see me. He told me he had been on a bender for a month and hadn't slept in days (he has a habit which upsets me as I am straight 180) I stayed the night and the next day 11am all friends came over and stayed all day and night doing drugs and drinking from 11am and my x joined in.I ended up leaving in the evening when they kept partying all night and I wanted sleep.

I rang him the next day he said he wanted to come to mine. I told him to come over he apologised and said he will never do drugs or alcohol again (same story every time) He was also broke, had lost his wallet and everything, smashed phone (typical scenario) He had no money to pay for his rent he was already 5 weeks behind. he said he wanted to move from his apartment I said he can stay at mine so he moved all his stuff to mine.

He spent every day on my couch "Recovering" from his bender with no money while i cooked ext for him every day. My grass needed cutting he didn't even bother at all until my uncle came and cut it. Last night I was at my mums (who dislikes him) and I got back home. He had gone through all my Facebook messages and my computer and all my USB's ect and got mad at me for things he found like old pics of my ex and whatever else that means nothing to me. I got very upset. He said he had to do it because he docent trust me when I have given him no reason not to. So today he went from the morning to have a meeting with his aunty as a business thing (he's always got new business ideas that he starts then throws away) i had a feeling he was with a girl. I questioned him asking "who was that girl u were with today?" as a test. he said he was with his 30 year old cousin that they spent the day together and had sushi and went for coffees all day. I didn't believe him. I got so frustrated from that and a few other little things (like he could have taken me out for dinner and spent the night with me instead he went to play tennis) and following my gut instinct and told him to take his stuff and leave.

He told me I was crazy and that Im making a big mistake but he didnt hesitate or seem upset about taking his belongings saying he wanted to anyways.

Did I make a mistake?
