scorpio male acting ...odd

Some history
Known each other for longer than a year. Have been "seeing" each other for 6 mths. Long distance-we hook up every 2 weeks or so. Chat all day, all night. I went to go visit him, stayed at his home for 4 days and it was awesome. Not uncomfortable at all. Unfortunately he has to stay in a hotel when he comes to my town because I have children and my place is teeny (twin bed hahaha-not accomodating to "visitors" if you get my drift)He likes to take pics and I swear he took 400 of them with me in "his enviroment".
I know that scorp males like to chill (unfold) with their emotions-that's cool. I have let him know I'm not the kind of girl who needs constant attention, or that wants his "stuff" (possessions etc). I have no issue finding stuff to do when I'm not talking to him.


Anyways...
About 2 weeks ago or so he started acting odd. Still msging me a lot. But not saying too much- but would get a little bummed out if I tried to let him go. A few times I decided not to let him go and just kept the convo going until I knew it was late and he fell asleep on the phone lol. He's not talking sexy as much but is now chatting about family and work projects he's doing. Also if I talk about wishing I could do some of the projects he's doing WITH him he gets super quiet-doesn't change the subject but is just really quiet. Before he would've said "oh yeah-that would be fun" And instead of getting excited about coming to see me-he can't stop talking about when I go to his neck of the woods. 0______o
WTH??
So my questions to all of you scorps (adore you all —) is..
#1- Is he trying to put me in the "friend zone?" By less sexy talk and more everyday talk?
#2- Is he hurt do you think by him not being able to stay at my place as I did his? (rejection) I told him the reasons why..
#3- Is he becoming bored? The lack of conversation on his part leads me to think that.

He's just acting sooo different than what he was. Its not a distancing thing- I became used to that in the beginning and had suggested that we take the weekend "off" from each other (unplug, no contact) as I thought this was what he needed/wanted. When I said this he said "no-it's ok". Exactly like that.
If he's getting bored I get it. Long distance things typically have an expiry date and I'm cool if he's not into it anymore. But I want to get opinions (ahhh Libra) before I jump to conclusions

Wouldn't it be logical to just ask him ^^^^this since you've been with him for 6mos? Because, you see, if you did ask him directly it can avoid a lot of assumptions on your part. One thing I would like to clue you in on, is the "letting him go" words you speak to him is probably leading him to assume you don't give a shit either way. So you might want to clarify that with him.

Thanks for the reply. I have asked 🙂 He gives me no concrete answers. Just runaround stuff.
Me -"Hey. Are you still cool with how things are going? How often we see each other? Our level of involvement?"
Him- "Well I'd like to see each other more for sure, but it's good. The times we see each other are great! How about you? Do you want more?" (cyptic)
Me- "Of course I want more! You make it hard no too! I have a great time with you 🙂"
.........silence.............
I change subject
Ahem
And "Letting him go" just means to sign off for the night. I have stuff to do and am bored with one sided conversation. Not cutting communication ^^
