Search Results: uncomfortable around boyfriend

So me and my boyfriend have been together for more than 1 year
Im 22 and he's 27
He has been living with few male housemates (around 8) and his house is such a shithole but its only 15 mins drive from my place
I feel uncomfortable when I come over anyway and he knows this and feels embarrased
The guys are dirty and dont clean after themselves
So he had enough and searched for other places to live
He found this apartment and its 10 mins away from his workplace but 30 mins away from my place and there is no train station nearby
he's the only one that can drive at the moment so he has to pick me up to and fro my place
So anyway, the landlord is a 24 year old female with a son
she's recently divorced and she goes to gym a lot (same as my boyfriend)
So now im getting worried about this
she's young and fit
He told me that she asked if he had a girlfriend and if he does, then he can bring his girlfriend over anytime or she can live with him
And he told her that he does have a girlfriend (me) and that i will be coming over regularly and she is fine with that
Should i be worried about his living situation?
What if he cheats with her?
She is full telling my boyfriend her whole life story how her ex husband was cheating on her with her flatmate
I don't know why she would tell my boyfriend this
by the way my boyfriend has never cheated during our relationship

I'm 15, my sister is 20 and her boyfriend is 22. They got here yesterday and this is our first time being around each other in person. He told me that I'm really beautiful and I don't mind, because it's a compliment. But, he also keeps staring at me and then smiles when he sees that I've noticed. When I was dumping my food down the garbage disposal in the sink and he was waiting, he just looked at me, laughed all loud in my ear and said "you're just so pretty." I thanked him but I felt really awkward, also because he was whisper-yelling all in my ear. Then when we were all sitting on the couch he started taking pictures of me and I asked what he was doing and he said he was posting "us" on Snapchat but he just took pictures of me 🙄 Earlier today I was walking to the bathroom and he just jumped up behind me and stuck his fingers in my sides to tickle scare me. They're staying in a hotel so I'm not worried about anything but he's just weird and makes me uncomfortable.
