How would you feel if your boyfriend's ex will be living with him for a month?

So this needs a lot of context... I'm F (23) and my boyfriend who is M (23) who i'll refer to as 'Jack'. This is my first relationship for me, and we are only 3 months into dating. We do not live with each other. We both live about a 10/15 minutes drive away. He has told me his housemate's little sister, who is also my boyfriend's ex, is visiting from overseas and will be living with them for one month. She will be staying in the bedroom next to his. I'll refer to the ex as 'Rachel'.

A year ago (last Christmas) they were a 'thing' and from what I can gather they were definitely fucking each other but were not boyfriend and girlfriend according to Jack at least. The weirder part is that Rachel has a boyfriend back in her home country. And he was apparently okay with it? And Jack seemed to think whatever they did, he was not cheating.

My boyfriend and I have talked about it several times, and I told him I obviously feel weird about it. Even weirder yet, his housemate (Rachel's older sister that Jack lives with), said she wants Jack to take Rachel out for touristy things. For example: going for a hike at waterfalls, to the beach, to the botanical gardens. To me it seemed quite weird for her to suggest to him to do those things with his ex? Especially since we haven't been dating for very long so I have not did all those things with Jack.

How would you react or feel in my situation? Jack acknowledges that the situation is fucked haha. Another thing to note, is Jack has been cheated on in the past by another ex. I don't want to be 'the jealous girlfriend' but I am new to dating and relationships. So I'm at a loss on what to do when she arrives.

How do I set clear boundaries? And not feel insecure about the situation? Should I suggest that my boyfriend should come to my apartment more during that time she's over?
