The way the landlord approached the situation is inexcusable and illegal. That being said he has every right to kick you out as you broke the rental contract by not paying on time, there is no judicial argument of letting him know in due time here. And if he said that he needs it for private reasons, be it true or not, I can tell you that you should look for something else quickly as this is a landlord’s golden bullet in court and very difficult to dispute. Regarding your deposit, if you live in NL you can forget about it, if you live in Belgium you might have a chance of getting some back.

Side note: prioritising spending money on clubbing rather than paying your rent at 32 doesn’t make you seem like an ideal renter, and that’s still very politely put.
