Hey, I need advice really badly!!!

So I am in a very very new relationship, to be honest I don’t even think we are officially dating but I think I made a mistake.

To start this off, this guy and I have known each other for about two years now. I’ve never been interested in dating much but I always had the biggest crush on him. So part of the problem is, I don’t know what we are!….maybe that’s my bad, I should’ve asked him sooner but we talk everyday, hang out a few times a week but most of the time we hang out things end up getting pretty steamy so sometimes I wonder if that’s what he’s after. We talk about some personal things but the past week or so we haven’t been talking quite as much…I know both of us don’t particularly like texting or talking on the phone so it’s not abnormal for us to not talk as much through text but something does seem weird, so because of that I guess I just was trying to keep things light. Well, I’ve been searching for a second job, and a mutual friend of ours sent me the link to a place that was hiring and informed me that the owner of the place was my “boyfriends” bosses wife. To be honest, I didn’t think a whole lot of it since it’s not like the company’s were connected, so I applied, especially because lately getting a job has been difficult so I didn’t think I would necessarily hear back. Well cut to the chase, I got hired and I still hadn’t mentioned anything to my “boyfriend” since I’ve been applying to so many jobs and I didn’t tell him every place I applied too, and given the situation him and I were in with us not talking as much, I just never mentioned it. I wasn’t trying to hide anything or be dishonest, I genuinely just forgot to bring it up with everything I have going on! One of the things I struggle with in relationships is telling people about myself! I’m a very closed of person and I never intend to be like that, I just get uncomfortable talking about myself. I mentioned to him that I had gotten a new job, he asked where it was but didn’t say much after that. Apparently he knew most of the time about all of this, our mutual friend had mentioned it to him I guess…so he knew this whole time. I know I sound like such an asshole for not mentioning it but for some reason In the moment when I was applying and everything, it didn’t really cross my mind that it was a big deal. I don’t think he’s super happy that I’m working with his bosses wife, especially that I never mentioned it to him. He didn’t express that he’s mad but I can tell, he seems a little weird, but I haven’t had the chance to really talk with him about it. My biggest thing is I didn’t realize what I was doing not only by applying, but not telling him about it. I probably seem like some crazy chick who’s trying to get myself involved in every aspect of his life…he probably thinks I’m a stalker or something. Ugh. I mean if I were him I might be a little weirded out too🤷‍♀️ and I think it’s pretty messed up that I didn’t say anything and I feel horrible. do I seem totally creepy for doing that? If anyone has any advice on how I should go about any of this I would appreciate it so much! And was I wrong for taking the job?
