What are We? What do I do??

About 6 months ago his relationship ended, although they still share a house for financial reasons.
kept it platonic until recently when things went further -

He hasnt responded in 2 days. I cant be sure he has got the message, but he has never not responded to anything before.

his current home situation to me, makes it impossible for us to be anymore than we are at the moment.

Hi,

I've known this guy for 2 and a half years, when we met we instantly clicked although nothing happened as he was in a relationship. About 6 months ago his relationship ended, although they still share a house for financial reasons.

Since then things with us have moved on, we've been meeting out in groups for drinks etc and kept it platonic until recently when things went further - I stopped them from going too far due to his home situation.

We have spoken since this but when we saw eachother I know I behaved differently than normal - I was offish and probably slightly cold towards him, eventhough he was stood infront of me tellng me how much he likes spending time with me. Not making excuses, I shouldnt have done it, past experience has shot my confidence and I put up these barriers to avoid getting hurt/let down. Knowing this, I messaged him to apologise for the way it may have looked and to say the way it come over wasnt the case at all. I just handled it really badly. He hasnt responded in 2 days. I cant be sure he has got the message, but he has never not responded to anything before.

I've been told by his friends and some of his family how much he likes me, and I believe this from the way that he acts when we are together however, his current home situation to me, makes it impossible for us to be anymore than we are at the moment. Am I right in thinking this? He has made comments that lead me to believe that he sees us as something more than friends but also that his current home setup is stopping him from really moving on with his life - which whilst I agree with this out of fairness to both of them, I wonder how long you can really let it go on without taking a step to move on with your life.

My main concern is that if I sit back too much, let him cool off and see what happens he wont know how I feel and I may end up losing him, whereas if I message again I'll look neurotic and scare him off as he has enough hassle and drama going on in other parts of his life, Im supposed to be the release from these not an addition to them.

Any advice greatly received as I think Im going insane!x
