Search Results: seeing an old friend

So we met a very interesting way to say the least. He says he hired a matchmaker to find me. She called my work phone one day and after review she is very reputable. It’s kind of like a millionaire matchmaker type thing. I was very hesitant for a few reasons. The age gap is more than I would normally be comfortable with (17 years) and he is extremely successful. That is great I just don’t like the feeling when people can “buy” anything they want. So we start going on lavish dates and decently early he pushed sex. We went on about 8-9 dates and were seeing each other 2-3x per week when it finally happened. Since he expects to every time which is fine, but he had seemed a little less interested in me. He is always commenting on my appearance which is nice to hear, but at the end of the day I want to know I am the one he is interested in being around not just looking at. He got sick and for 2 weeks acted extremely distant. I took him gifts etc. Yesterday kind of out of nowhere he started asking all the things I liked as he wants to know so we can do them together and was very chatty, but then he said he had a work dinner. That’s fine, but I sent him a few texts and nothing. To give an idea I usually get 2-5 texts from him a day and the more I am around him the more his phone is around. Now he does work a lot as he owns a few businesses, but I’m not sure I’m the only one in his life. I just feel like I’m getting mixed signals. We have now been on about 20 dates over 2 months and are now on a schedule of 1-2 dates per week. How much am I overthinking this? I just keep coming back to the fact he hired someone, date 2 he said he put his matchmaker membership on hold, date 3 he told me he told his mom about me, he deleted his Instagram right after we started dating, but kept his facebook (we aren’t connect on). He has never said much of anything about his friends or me meeting them. He has never asked about meeting my friends. Thoughts?

So, I started uni this September. Eventually the only option that turned up was living with 5 guys that were a year older than me.

Most people would think that’s insane but I have always gotten on a lot better with guys over girls, mostly because I grew up with two brothers, I’m quite outgoing and dislike the kind of drama girls get themselves involved it.. so as a result most of my friends are guys so.
After about a week, I got together with the guy I was living with that I fancied. After the first night we spent all of the following day together and then from that week on we slept in the same bed together up until now, his bed. It’s now been six weeks of us sleeping together and cuddling/hanging out with each other during the day.
Recently, although he hadn’t done anything to make me question him, I started to get nervous and feel like he was losing interest in me even though I don’t think he was acting any differently. So I decided to test him a bit, so I was going to bring up the topic of whether or not we were seeing other people after we got home from a night out.
But, while we were out my other housemate was trying to set me up with other guys although he knows I have been seeing his best friend for the past while, I thought it was odd that he was doing this and then I started to wonder does he know something I don’t?
Then later that night in bed, I asked the guy I was seeing “how would you feel if I was with another guy some night?” he said I can see other guys if I like but that he wants to know who they are if i do, but over all he acted quite calm and not too bothered.. so now I am panicking because I assumed he would ask me not to see other people but when he didn’t I felt like all my fears were true and maybe he really was losing interest?
Am I just an easy option for him because I live with him?
since this happened he has continued to act the same as he always has with me but I just can’t help but think my instincts are right.. what do ye think?
