Communication/emotional issues?

So I’ve been seeing/talking to the same guy since late November/early December. He’s very shy and quiet most of the time. And we have had discussions about it along with our flaws and he openly talked to me about him not having any confidence and that it’s hard for him to let people in. He hasn’t went into detail of why and I’m not going to push someone until they want to open up (to an extent obviously). But he made the statement that he trusts me but he has issues with trusting people and said “you’ll see why soon enough”. Which I didn’t question it because when he’s ready to open up and talk about his past/emotions he will. Well, when he was out of town one of his friends had messaged me asking when we were going to hang out (they weren’t together either). I thought he wanted to hang out so I can introduce him to some of my single friends because the week before he wanted me to bring them to the bar where i met my guy and his friends but all but one of my friends were busy. I told his friend “as long as he’s cool with us hanging out, I’m okay with it, and I’ll introduce you to some of my friends that you want to meet so badly😂”. He then messaged me back saying “or you could come stay with me tonight”. Which I knew he was insinuating “hey come stay with me and we can mess around”. I immediately rejected him and said not going to ever happen. So I messaged my guy saying I need to talk to you whenever you get time. Next day he asked what I wanted to talk about. I told him everything, his response was “oh okay well thank you for telling me.” I said I’m sorry I had to tell you but I wouldn’t had felt right if I didn’t say anything, he said “I completely understand. Thank you.” Ever since then he has been more distant towards me, not talking as much. I asked him tonight “are you okay because you have said much lately. I didn’t know if I said/done something wrong, figured I’d ask” he says “you haven’t “ and simply stated he was just exhausted and about to pass out. I just have mixed emotions because it’s like I’ve bothered him or whatever is bothering him he’s putting on me even though I haven’t done anything wrong. Like what do I do? He is a very sweet guy and I don’t find a lot of people that I’m actually interested in often. I don’t want to push him but at the same time I shouldn’t have something taken out on me if the issue is about what his friend done. So ladies please give me some advice....or give me some insight at what the real issue is or why he’s acting like this.
