Search Results: getting over, cheating boyfriend

Okay well I didn’t plan on this happening but I live with my abusive boyfriend who I don’t love but am scared to leave. He hit me one day and told me to find someone else. I did that and met my coworker. We started just as friends with benefits. It was nice at first he had an ex girlfriend who basically is abusive Nd fights girls he tries to talk to. I am still living with my abusing boyfriend. Then we started to fall in love. We started catching feelings both of us started getting jealous but then I guess one day it just clicked we had feelings for eachother, he can’t express himself so he never fully says what he thinks. He started getting jealous over my boyfriend and I told him I liked him and wanted him. It is bad to cheat I know but it felt like I needed to talk to him it felt like time stopped all around me when I met him. He just kinda beats around the bush and will say he wants to be with me. I then told him I’m really depressed and he said why are you depressed when you have me now? He then doesn’t really answer my calls and texts and it’s just like he says he wants me but then acts a different way on social media and texting. I can’t help but feel love. I don't know why this happened this way

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
