Have you tried talking with him about it? Not necessarily going into too much detail, but mentioning the different love language you both use for example.
I feel like you should probably work on yourself instead of worrying about a relationship right now, it’s only gonna turn toxic if this is your mentality with him
I think it would really help you if you told him about your love language part. Personally, he looks like a guy who minds his own business and the emotional cheating part, yeah there are some guys like this who don’t share with SO. So don’t worry about that part. It would be best that you tell him about the love language part and tell him that it makes you anxious, I’m sure he’ll understand and help you out. Good luck.
