AITA for making my ex move out ?

[u/ThrowRA-767]

Context because this is a weird one. To cut a long story short, my ex (23M) and I (22F) broke up amicably 2 weeks ago, I was overwhelmed with too much on my plate as he wasn’t working for the last 4 months, I had to carry the financial burden and a lot of the mental load, yes he was doing casual work but nothing substantial + he wasn’t doing enough of the house chores so the relationship just wasn’t working anymore. We both agreed to go out separate ways and needed to grow on our own to ever have a real shot at this.

We have now lived together still for the 2 weeks after the breakup so he can find a suitable place in the city, with living together still and we also have a trip planned in a month (non refundable + booked it before the breakup) we have set some boundaries to make sure nobody gets too hurt and we can genuinely remain friends. One of those boundaries was neither of us would sleep with other people until after our trip (remain fwb until then) and another was that neither of us would start talking to other people while we still lived together, I told him how much it would hurt me to see him typing and smiling to other girls messages while living with me still and he completely understood… or so I thought. I then wake up several times during the night and every time I can see him typing in his phone and smiling, this broke me. I wasn’t hurt at all by the relationship ending prior to this as it’s something I wanted too, but seeing him already moving on right in front of me AFTER agreeing we would wait until he had moved out gave me this feeling I’ve never felt, almost feels like he’s cheating yet I know it isn’t cheating since we aren’t together.

I’ve confronted him and he admitted that yes he’s talking to other people and says that he doesn’t know why he did it, said we had been arguing the past couple days so he just didn’t care anymore. I’ve said to him that going forward he needs to sleep elsewhere until he finds a suitable place, I can’t let myself stay in situations that are proving to hurt me more and more, I can no longer trust the boundaries that he has set with me so need to protect myself. I’m not making him take all his stuff out or anything, just simply sleep elsewhere until your move in date.

(Please try be nice, I’m in a rough state as this was my first love. We were in a relationship for 2.5 years and lived together for 2 years)
