Good morning!  Thank you for your post.  It sounds like you're having a pretty confusing time, and that can be really rough.

I wonder whether you are feeling a bit invaded - it sounds like you feel like he's in your space or intruding when he messages you, which is very tricky.  In my opinion it's normal for him to be saying that he likes to spend time with you and that he likes you.  That's appropriate for a couple of months in; he's just expressing how he feels and what his intentions are.  It sounds as though he's interested in you and in spending time with you, as he messages you first and initiates contact.

Now for the tricky bit I suppose - do you actually like him?  I felt as though, whilst it's good "on paper", you're feeling overwhelmed even seeing him once a week.  I think it's more often the case that people in the first throes of a relationship might want to see each other more often, actually (although obviously there's no right or wrong way) - but it might explain why he seems more keen than you are.  He may well have the expectation and desire to spend more time with you than you actually feel okay with. 

SO...what I'm getting round to is this.  Relationships are ace - if you want one.  If you want a mate with similar interests to hang out with - also, ace.  The thing is though, you have to both be able to engage in it in a way that is okay for you.  That's a big factor in compatibility too, as well as having similar interests and views, etc.  It's hard to say anything definitive based on one brief post and not knowing you in person, but it's okay if you don't want it.  You don't need a "good reason" - your not feeling comfortable is a perfectly valid reason.  Just because someone is nice, or right "on paper", it doesn't mean they're the right person at the right time, etc.  It's really okay if you don't feel comfortable to say 'I don't feel comfortable'.

That being said, the flip side is that if you DO like him, it can sometimes feel scary and overwhelming when they like you back, as being in an intimate relationship with someone does take some adjusting to - one of the biggest points being that you have to feel okay about letting them in a bit, or it can't really be very intimate!  Sorry if that was quite a rambly response - intimacy and romance is complex and challenging, or it wouldn't continue to be such a focus and source of inspiration in the wider consciousness.  Without knowing you and him in person it's hard to give a perfectly accurate response but hopefully there is something in there that made some sense!
